Patent ID: 7964877

Claim:
A semiconductor light emitting device comprising a semiconductor structure including a first conductivity semiconductor layer, an active layer and a second conductivity semiconductor layer sequentially stacked, wherein the semiconductor structure further includes a plurality of grooves extending from the second conductivity semiconductor layer with a depth reaching to at least an inner part of the active layer in order to divide the active layer, and a plurality of light guide parts being separated from each other by each of the plurality of grooves and alternating with the grooves thereof, the light guide parts having a length greater than a width thereof to selectively emit a polarized component in a length direction thereof, the grooves are arranged along one direction of the width of the light guide parts, the semiconductor structure comprises a first and a second reflective layers, between which the active layer is interposed, and the light guide parts and the plurality of grooves are disposed between the first and second reflective layers.
