Abstract :
A novel monolithic programmable optical lattice filter consisting of unit cell building blocks is proposed. Single unit cells incorporating a ring resonator in one arm of a Mach-Zehnder are fabricated in an InGaAsP-InP material system. Programmable poles and zeros are demonstrated and monolithically cascaded unit cells are used to synthesize a flat passband.
