    • A surface-emitting laser (100a) comprises an active layer (3) formed on a semiconductor substrate (2a) and a pair of upper and lower electrodes (5, 6) for injecting carriers into the active layer (3). The lower electrode (6) is shaped into a star when viewed from above so that the density of the current injected into the active layer (3) from the lower electrode (6) is high at the center of the lower electrode (6) and low at its periphery part. The density distribution of the carriers injected into the active layer of the surface-emitting laser (100a) corresponds to the power distribution of the light inside the active layer. As a result, hole burning due to an increase of the current density in the region corresponding to the peripheral part of the electrode does not occur in the active layer, and the transverse mode stability during high output operation is drastically enhanced, thereby improving the high-output characteristic.
    • 表面发射激光器(100a)包括形成在半导体衬底(2a)上的有源层(3)和用于将载流子注入有源层(3)的一对上下电极(5,6)。 当从上方观察时,下电极(6)成形为星形,使得从下电极(6)注入有源层(3)的电流的密度在下电极(6)的中心处高,并且 在其周边部分较低。 注入到表面发射激光器(100a)的有源层中的载流子的密度分布对应于活性层内的光的功率分布。 结果,在有源层中不会发生由于与电极的周边部分对应的区域中的电流密度的增加而导致的空穴燃烧,并且高输出操作期间的横向模式稳定性急剧增加,从而提高了高 输出特性。
