<p>SEMICONUCTOR LIGHT EMITTING DEVICE A light emitting device comprising a first confinement layer, an active layer having a vee-shaped groove therein extending from a surface thereof towards the first confinement layer and a second confinement layer filling the groove and overlying the surface of the active layer. Electrical current flowing in the device flows through the grooved portion of the active region thereby providing confinement of the current and the light beam emitted by the device in the plane of the active layer.</p> |
