Micro-Disk Modulator

Caption

This is an illustration of a silicon photonic micro-disk modulator operating at cryogenic temperatures. Light traveling down the silicon waveguide couples to the resonance of the micro-disk cavity. An electrical signal applied to the disk shifts the resonance and as a result modulates the light passing through the waveguide. (Rendered by Hanqing Kuang)
