System having light sensor with enhanced sensitivity |
摘要 |
The optical device includes a waveguide and a light sensor on a base. The light sensor includes a ridge extending from slab regions positioned on opposing sides of the ridge. The ridge includes a multiplication layer and an absorption layer. The absorption layer is positioned to receive at least a portion of the light signal from the waveguide. Additionally, the absorption layer generates a hole and electron pair in response to receiving a photon of the light signal. The multiplication layer is positioned to receive the electron generated in the absorption layer and to generate additional electrons in response to receiving the electron.
