Abstract
We demonstrate the smallest microring modulator to date, with 1.5 µm radius, record 8.5 THz FSR and 30 GHz/V O-band shift efficiency, using a MOSCAP structure in a new 45 nm monolithic CMOS electronic-photonic process (45CLO). It could enable massively-parallel optical links with low energy and high bandwidth density.
