Abstract :
Novel monolithic programmable optical filters are proposed and demonstrated. Deeply-etched waveguides are used throughout. Unit cells, incorporating a ring resonator in one arm of a Mach-Zehnder, have given programmable poles and zeros; cascaded unit cells have yielded flat-topped band-pass filter characteristics.
