    • The invention provides a semiconductor light emitting device whose operating voltage can be easily reduced, a method of producing the same, and an optical device. An n-type clad layer, a first guide layer, an active layer, a second guide layer, a p-type clad layer, a first semiconductor layer, and a second semiconductor layer of ZnSe are successively grown on an n-type substrate. An alkali compound layer of Na2Se is then formed thereon. Subsequently, a heat treatment is performed by means of irradiation of an excimer laser beam so that at least a part of the second semiconductor layer and at least a part of the alkali compound layer are altered thereby forming a contact layer. Furthermore, a p-side electrode is formed on the contact layer. The contact layer contains an alkali metal serving as a p-type impurity so that the contact layer has a low electric resistance thereby achieving a reduction in the operating voltage and thus a reduction in the operating power. As a result of the reduction in the operating power, the device life is improved.
    • 本发明提供一种可以容易地降低其工作电压的半导体发光器件,其制造方法和光学器件。 在n型衬底上依次生长n型覆盖层,第一引导层,有源层,第二引导层,p型覆盖层,第一半导体层和第二半导体层。 然后在其上形成Na 2 Se的碱性化合物层。 随后,通过照射准分子激光束进行热处理,使得第二半导体层的至少一部分和碱性化合物层的至少一部分被改变,从而形成接触层。 此外,在接触层上形成p侧电极。 接触层含有用作p型杂质的碱金属,使得接触层具有低电阻,从而实现工作电压的降低,从而降低工作电力。 由于操作功率的降低,设备寿命得到改善。
