摘要：
The paper presents the results of numerical analyses of optical structures realized in the form of planar waveguides made of materials with high values of the refractive index n a parts per thousand 1.85. The analysed structures consist of a waveguide and input-output systems. Input-output couplers are realized in the form of prisms as well as Bragg's grating couplers. Numerical investigations were carried out by applying the finite difference time domain (FDTD) method.
