Performance of integrated optical filter consisted of input and output waveguides and ring resonator was analyzed numerically. In order to obtain component of electromagnetic field Ez scalar wave equation was solved via the finite-difference time-domain (FDTD) method. Wave equation was supplemented with term proportional to the first derivative of Ez on time to simulate processes compensation of loss. Snapshots in time of FDTD-computed electromagnetic field obviously illustrate excitation process of ring resonator. Increase of transmission coefficient and transient curves determining operation speed of device are presented.
