Abstract

A photonic integrated circuit for modulating light includes an electro-optic modulator disposed along a top surface of a substrate. The electro-optic modulator includes an optical waveguide segment connected between two optical waveguide loop mirrors. At least one of the two optical waveguide loop mirrors includes a Mach-Zehnder modulator (MZM) having a pair of 2x2 optical couplers at opposite ends thereof to couple light in and out of the MZM, one of the 2x2 couplers being terminated by a waveguide loop.
