Computer modeling of fiber-optical and integrated-optical structures

Finite-difference techniques in the frequency domain (FDFD) method was used for calculation of the integrated-optical structure. As an example of the structure the signal distribution between optical waveguides linked by the ring resonator was investigated. The amplitude-frequency dependence for the structure was calculated with a spectral method. The used method allows to calculate not only exact position of spectral components, which correspond to the same one calculated analytically, but can also predict the relation between amplitudes of spectral components.
