Abstract:Low driving voltage (Vpp), high-speed silicon microring modulator plays a critical role in energy-efficient optical interconnect and optical computing systems owing to its ultra-compact footprint and capability for on-chip wavelength-division multiplexing. However, existing silicon microring modulators usually require more than 2 V of Vpp, which is limited by the relatively weak plasma dispersion effect of silicon and the small capacitance density of the reversed PN-junction. Here we present a highly efficient… Show more
