Abstract :
The theory is developed for a narrowband distributed feedback reflector that reflects at the center of the grating stopband and transmits at frequencies to either side. A perturbational method of analysis is presented which simplifies the algebra and provides helpful insight. The approximate analysis is compared with the exact results. It is shown that the approximate solution is good in the operating region of practical devices. The proposed tunable narrowband reflector can perform well at a reasonable bandwidth of about 40 GHz
