摘要： A semiconductor laser device having a smooth cleavage plane is provided. The provided laser device includes a current injection ridge and force distribution ridges formed adjacent to the current injection ridge, which protrudes from an upper surface of a mesa structure. The mesa structure is formed of multi-semiconductor material layers including a laser resonance layer and cladding layers disposed above and below the resonance layer. The current injection ridge and the force distribution ridges distribute a scribing force when cleaving the laser device so that the smooth cleavage planes are obtained. Defects are prevented in the current injection ridge due to the distribution of force when bonding flip chips.

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.
