摘要
Various embodiments of a micro-disc modulator as well as a silicon photonic device and an optoelectronic communication apparatus using the micro-disc modulator are described. In one aspect, a device includes a SOI substrate and a silicon photonic structure formed on a primary surface of the SOI substrate. The semiconductor substrate includes a silicon waveguide and a micro-disc modulator. The micro-disc modulator is adjacent to the silicon waveguide and has a top surface substantially parallel to the primary surface of the SOI substrate. The top surface of the micro-disc modulator includes one or more discontinuities therein. The micro-disc modulator may be a multi-junction micro-disc modulator having two vertical p-n junctions with a single resonance frequency to achieve high-speed modulation and low-power consumption.
