title: Microring quadrature modulators.
abstract: A high-Q microring integrated with a dual-2x2-Mach-Zehnder interferometer coupler is proposed as a low-chirp, low-distortion, low-drive-power, quadrature modulator capable of M-ary quadrature amplitude modulation and phase-shift keyed outputs. The modulation rate can greatly exceed the resonator linewidth and is limited only by the coupler response or free spectral range.
