    Opis:
    The basic building block of every photonic circuit is a waveguide. In this paper we investigate the most popular silicon waveguide structures in the form of a silicon-on-insulator rib waveguide. We also analyse two structures that can find applications in mid- and long-wave infrared regions: free-standing and hollow core omnidirectional waveguides.

    Opis:
    In the paper a special form of the generalized nonlinear Schrödinger equation in saturable medium with nonlinear dispersion and the self-frequency shift terms is considered. The solutions describing both the intensity and phase profiles of grey solitons propagating in this medium are obtained. Four cases of medium with or without saturation and with or without higher order terms are considered. For a square-two-level model of saturation analytical explicit solutions are derived. The relations between the medium and propagation parameters of solitons are discussed.

    In the paper the propagation of short pulses in nonlinear Kerr-like medium is considered. Pulses are described by the nonlinear Schrödinger equation in which the generalization of nonlinear dispersion term and the self-frequency shift are taken into account. The solution of the equation in the form of quadrature is derived. Both the phase and profile of the pulse intensity are obtained. The cases of propagating bright and dark solitons in saturable Kerr-like medium are analyzed. Two models of saturation are considered. The explicit analytical expressions describing the Kerr limit are reported. The relations between the medium and propagation parameters are thoroughly discussed.

    The paper presents optimizing investigations by the beam propagation method method of two-wave multi/demultiplexer which uses gradient index multimode interference structures made by $Ag^{+}-Na^{+}$ ion exchange in BK-7 glass. We have discussed the influence of the structure geometry and technological process parameters for selected wavelength combinations within the range of 635÷ 850 nm. We have described operating parameters of the multiplexers - excess losses and contrasts. We have also presented the way of finding approximate MMI section widths and lengths which satisfy the multiplexing condition.

    Opis:
    It is well known that the conversion efficiency of the SHG in the Čerenkov regime in a waveguide with a nonlinear substrate exhibits a very sharp peak. Its position in a "pump wavelength-guide thickness" diagram follows a modified dispersion relation. A particular material combination exactly determines both the pump wavelength and the guide thickness. The existence of the peak was also experimentally proved with relatively high normalised conversion efficiency of 210%/(cm W). However, in order to achieve such a high conversion efficiency, the required tolerance in the guide thickness should be smaller than 0.5 nm (the FWHM of the peak is approximately 0.8 nm). The allowed variations in refractive indices are also very low (<10$\text{}^{-3}$). The recent theoretical study of the authors showed that an additional layer (idler) inserted into the waveguide facilitates more degrees of freedom which could relax the conditions for reaching the efficiency peak. This paper presents a detailed study of the behaviour of four-layer waveguide devices with a nonlinear substrate which promise a less constrained way to reach the efficiency peak.

    We present a study of the Cerenkov configuration second harmonic generation in X-cut ion-implanted lithium niobate waveguides. An approximate solution of conversion efficiency is given and plotted which shows that it is very sensitive to the waveguide depth and pump wavelength. The results can be used in the design of waveguides for the efficient second harmonic generation in the Cerenkov configuration.

    Opis:
    This work focuses on the study of the influence of geometrical parameters on the quality factor of a cavity H1, realized with one missing hole in the center. For obtaining the H1 characteristics and the band structure of the photonic crystal, the finite difference time domain (FDTD) method, which is based on solving Maxwell's equations in a spatially and temporally discretized domain, and plane wave expansion (PWE) method, which is a resolution method of Maxwell equations in the frequency domain, were used respectively. In this method, one simulates a space of theoretically infinite extent with a finite computational cell. The quality factor increases until a maximum value equal 1.23×10⁶ for a filling factor r/a=0.44, and then decreases to a value of 3.39×10⁵ for a filling factor r/a=0.47.

    By operating an AlGaAs waveguide array at the half band gap, we experimentally demonstrate basic features of discrete systems, which do not appear in the corresponding continuous counterpart - the slab waveguide. Under selected initial conditions, we observed nonlinearly induced locking of an initially moving soliton to the input waveguide. If the power is even higher, originally locked beams start to move again, but in a direction opposite to the initial tilt.

    Planar waveguides in which some range of the waveguide was modified by depositing on it a layer of some other dielectric, are called composite optical waveguides. Such a structure is based on a planar waveguide obtained by means of ion exchange $K^+-Na^+$ on glass, and covered by an adequately profiled dielectric layer. This kind of structure is of much interest due to considerable possibilities of taking measurements, which may contribute to a further development of the optoelectronic sensor. Especially required are sensor systems in chemistry, biochemistry, biotechnology, and others. Investigations on the properties of composite layers constitute a continuation of investigations concerning the construction of interferometers, which are very sensitive, cheap and easy to be produced.

These investigations have made it possible to determine the optical spectral range in which this material is transparent as well as the edges of absorption. The presented investigations are valuable particularly concerning the application of zinc oxide in optoelectronic and photonic structures as well as in systems of waveguides and sensor layers of integrated optics.

    One-dimensional optical waveguide calculations were performed to study the dependence of waveguide design on confinement factor (Γp) and optical losses ($\alpha_i$) of nitride laser diodes for emission wavelength ranging from 405 nm to 520 nm. We found that the conventional waveguide design containing GaN waveguide and AlGaN cladding layers known from violet laser diode does not support sufficient confinement of the optical mode for long wavelength devices (λ > 450 nm). We proposed a new design consisting of a thick InGaN waveguide which enhances the confinement. We compared the theoretical predictions with laser diodes grown by plasma assisted molecular beam epitaxy.

    We discuss the possibility of light control by means of light diffraction by space charge waves which are the periodic domain trains induced at some circumstances in GaAs Gunn effect diode. The two possible regimes of the proposed device are considered: the first one which is analogous to the Bragg diffraction in case of light-acoustic diffraction and the other one, which we call "intermediate", since the parameter Q which distinguishes the Raman-Nath (Q<1) and the Bragg diffraction (Q>10), in this case is≈1 (actually, only bit smaller than 1). Among the advantages of this hypothetical device are the simpler control of operation and perhaps, possibility to couple it with the waveguides and switchers for surface electromagnetic waves and other miniaturized photonic circuits.

    In the paper, the results of technological investigations on planar optical waveguides based on high band gap oxide semiconductors were presented. Investigations concerned the technologies of depositing very thin layers of: zinc oxide ZnO, titanium dioxide $TiO_2$ and tin dioxide $SnO_2$ on substrates of quartz glass plates. There were investigated both morphological structures of the produced layers and their optical properties. The paper also presents investigations on the technology of input-output light systems in the Bragg grating structures.

    Opis:
    In this paper, we investigate semiconductor nanowaveguides (i.e. ridge waveguides with core-widths narrower than 1 μm) intended to act as novel optical light sources through nonlinear wavelength/frequency conversion. In particular, numerical calculations have been performed in order to design suitable photonic devices (fabricated in the AlGaAs/GaAs platform) capable of high efficiency second harmonic generation. Particular interest has been dedicated to the effective conversion of optical signals from 1520-1600 nm (the third telecom window) down to 760-800 nm. We demonstrate that the output wavelength (resulting from modal phase-matching) can be dynamically tuned by proper adjustment of the temperature and/or geometrical parameters of the waveguides. In addition, by changing the waveguide width it is also possible to modify the device dispersion characteristics, giving the possibility to work in the region of anomalous dispersion and thus allowing for the generation of temporal solitons.

    Opis:
    In this paper an analysis of two types of planar waveguides (with the conventional type of the layer and the reverse symmetry waveguide) is presented. In both types of the structure the polymer SU8 was used. In respect of its properties, this polymer is suitable as a waveguide layer. The analysis presented in this paper describes those structures working as sensors. We made a comparison of both types of configuration. We made a detailed analysis of the sensitivity of the covering layer when the thickness of the waveguide layer is changing and when the length of the wave activating the structure is changing, too.

    The paper presents the results of investigations concerning the measurement of the attenuation of planar waveguide structures obtained by means of the photopolymerization of the polymer SU8. The applied substrate was sodium-calcium glass. Attenuation is one of the fundamental parameters of optical waveguide, the knowledge of which is of crucial importance in the construction of various kinds of optical sensors. A method of its measurement has been presented, consisting in the recording of the intensity of scattered light making use of CCD camera. The paper deals also with the generation of planar polymer waveguide, taking into account problems connected with the adhesion to glass substrates.

    This publication presents experimental measurement methodology which allows to determine the characteristics of sensitivity planar differential interferometer. To confirm data reliability additional measurements were done such as simulations in OptiBPM software by Optiwave. Curves received from two methods: experimental and theoretical, were summed up and compared. Conclusions were made on their basis, for example the influence of used wavelengths or refractive index of single mode waveguide cladding on curves of sensitivity differential interferometer using planar waveguide received from the ion exchange method.
