Abstract

A device structure for implementing a continuously tunable optical filter is described. The proposed filter relies on the creation of a resonant optical cavity between a high-reflectivity mirror and a periodic grating, with a phase control section in between. The filter has only one transmission peak over the entire frequency range, can be tuned in a few nanoseconds, and is suitable for integration with the receiver in a photonic circuit. >
