ABSTRACT

Optical signal processing components, such as optical modulators, sensors, all-optical integrators, and differentiators implemented on a chip, are important for developing computer technology. Analog signal-processing applications include all-optical solution of differential equations of various orders. Integrators and differentiators based on Bragg gratings are a few millimeters in size. Integrators and differentiators based on ring resonators are more compact. The model of a two-component nanocavity is also described. In this model, the minimum details of the structure are found only in the periodic component of the resonator. The optical modulator is one the most important optical signal processing components. The optical resonant sensors demonstrate good compatibility with the requirements of the microfluidics. The resonance cavity characteristics were computed using the parallel three-dimensional (3D) finite-difference time-domain method. The resonance cavity regions that contain the nonlinear material are characterized by a smaller refractive index than that of the waveguide.
