This paper describes filter designs for converting digital bandpass filters to a photonic integrated circuit (PIC). Because the filter designs must be physically realizable in an optical system, we consider a structure that not only meets the bandpass design requirements, but yields transfer function poles that avoid lasing. We consider a combination of(More)
A practical implementation of an optical filter must have a mechanism to compensate for variations in the component parameters-especially for an infinite-impulse-response (IIR) filter which can enter lasing mode if the poles are too close to the unit circle. Temperature changes are a frequent cause of unwanted drift in the parameters of the various optical(More)
