摘要:
A light source for a photonic integrated circuit may comprise a reflection coupling layer formed on a substrate in which an optical waveguide is provided, at least one side of the reflection coupling layer being optically connected to the optical waveguide; an optical mode alignment layer provided on the reflection coupling layer; and/or an upper structure provided on the optical mode alignment layer and including an active layer for generating light and a reflection layer provided on the active layer. A light source for a photonic integrated circuit may comprise a lower reflection layer; an optical waveguide optically connected to the lower reflection layer; an optical mode alignment layer on the lower reflection layer; an active layer on the optical mode alignment layer; and/or an upper reflection layer on the active layer.
摘要:
A photodetector (100) includes a waveguide (120) on a substrate, and a photodetection portion (130) connected to the waveguide. The photodetection portion includes a first insulation layer (132), a graphene layer (133) on said first layer (132), and a second insulation layer (134) on the graphene. A first electrode (141) and a second electrode (142) separated from the first ridge portion (131) and electrically connected to the graphene.
