Patent ID: 7919784

Claim:
A semiconductor light-emitting device, comprising: an upper cladding layer; a lower cladding layer; an active layer between the upper and lower cladding layers; an upper ohmic-contact layer forming a conductive path to the upper cladding layer; and a lower ohmic-contact layer forming a conductive path to the lower cladding layer, the lower ohmic-contact layer having a shape that is substantially complementary to the shape of the upper ohmic-contact layer, wherein the lower ohmic-contact layer is formed by removing a portion that is substantially overlapping vertically with the upper ohmic-contact layer, thereby diverting a carrier flow away from a portion of the active layer which is substantially below the upper ohmic-contact layer when a voltage is applied to the upper and lower ohmic-contact layers: wherein the removed portion of the lower ohmic-contact layer is filled with a metal material capable of forming a Schottky contact with the lower cladding layer.
