摘要	A vertical cavity surface emitting laser (VCSEL 10) including two undoped distributed Bragg reflectors (DBRs 16,18) and an undoped active region (14) therebetween, and employing lateral current injection to the undoped active region (14) minimizes optical loss within the laser. A periodic gain structure may also be employed in the VCSEL (10), thus maximizing gain in the undoped active region (14). The undoped distributed Bragg reflectors (DBRs) in the VCSEL, reduce the optical loss within the cavity.
其他摘要	垂直腔表面发射激光器（VCSEL 10）包括两个未掺杂的分布式布拉格反射器（DBR 16,18）和在它们之间的未掺杂有源区（14），并且对未掺杂的有源区（14）采用横向电流注入使得在其内部的光学损耗最小化。激光。在VCSEL（10）中也可以采用周期性增益结构，从而最大化未掺杂有源区（14）中的增益。 VCSEL中的未掺杂分布式布拉格反射器（DBR）减少了腔内的光学损耗。
