单片宽调谐激光二极管通常采用复杂的光栅结构，利用游标效应实现宽波长调谐。然而，这些光栅的反射光谱容易受到任何非预期反射的影响，从而引起干涉效应并损害激光器的调谐性能。这种反射的主要来源是设备的正面和背面。它们对调谐特性的影响是显著的，将在这封信中讨论。此外，还提出了一种统计良率分析，将器件良率与重要的设计参数联系起来。
Monolithic widely tunable laser diodes commonly employ sophisticated grating structures to achieve wide wavelength tuning by exploiting the Vernier effect. The reflection spectra of these gratings are, however, susceptible to any unintended reflections, which cause interference effects and impair the tuning behavior of the laser. The main source of such reflections are the front and rear facet of the device. Their influence on the tuning characteristic is significant and will be discussed in this letter. Furthermore, a statistical yield analysis is presented, which relates device yield to important design parameters.
