    摘要: Provided are a semiconductor laser diode having a current confining layer and a method of fabricating the same. The semiconductor laser diode includes a substrate, a first material layer deposited on the substrate, an active layer which is deposited on the first material layer and emits a laser beam, and a second material layer which is deposited on the active layer and includes a ridge portion protruding from the active layer and a current confining layer formed by injection of ions into peripheral portions of the ridge portion so as to confine a current injected into the active layer. Therefore, it is possible to fabricate an improved semiconductor laser diode having a low-resonance critical current value that can remove a loss in an optical profile and reduce the profile width of a current injected into the active layer while maintaining the width of the ridge portion.
