Abstract

One embodiment of the present invention provides a semiconductor light-emitting device, which comprises: 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 the lower cladding layer. The lower ohmic-contact layer has a shape substantially different from the shape of 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.
