使用光面透镜，使LED光色更佳，光斑均匀集中，无杂色，无阴影暗区。
With smooth lens, the LED light color better, even centralized spot, no noise, no dark shadows.
为了提高脊波导结构的超辐射二极管（SLD）与单模光纤的耦合功率，研究了有源区与脊之间的残留层和上光限制层的厚度对SLD输出功率和近场光斑的影响。
With the aim of achieving high coupling power of RWG SLDs into SMFs, the structure dependences of the output power and the near field pattern are investigated.
