Abstract
A novel ring resonator configuration with Bragg gratings is presented. The stability of this configuration is studied by a z-transform technique. A router design with a FWHM of 17 MHz, a -40-dB rejection ratio, and a 15-dB gain at the output port is reported. The influence of temperature and of fabrication tolerance on parameters of this router configuration implemented with fiber technology is reviewed. Deviations in design specification owing to parameter variations are studied and compensated for with a gain control of 2.4% in a specific design
