Abstract :
Active optical filters which use distributed feedback or distributed Bragg reflector structures have narrow bandwidths, large free spectral ranges and may be tunable. Their main drawback is a small dynamic range, determined on one hand by the internal filter noise and on the other hand by gain saturation at relatively low input powers. This paper describes small- and large-signal characteristics of active filters based on two-section DBR structures
