摘要 | A semiconductor laser capable of emitting in any one of standard communication wavelengths is of great practical value. To this end, a single semiconductor chip is fabricated on which many different distributed feedback (DFB) lasers are integrated. The device parameters of the different DFB lasers are varied such that each laser emits at a different wavelength. In addition a micro-mechanical optical element is packaged with the laser array, such that the position of the optical element controls which laser stripe is coupled to the output fiber. The micro-mechanical element or switch in various embodiments is a sliding waveguide, a movable lens, or a mirror that tilts. By selecting the particular DFB laser, controlling the temperature to fine tune the wavelength, and adjusting the position of the micro-mechanical optical element, the output wavelength is set to one of many communication wavelengths. |
其他摘要 | 能够以标准通信波长中的任何一种发光的半导体激光器具有很大的实用价值。为此,制造单个半导体芯片,其上集成了许多不同的分布反馈(DFB)激光器。改变不同DFB激光器的器件参数,使得每个激光器以不同的波长发射。另外,微机械光学元件与激光器阵列一起封装,使得光学元件的位置控制哪个激光条纹耦合到输出光纤。各种实施例中的微机械元件或开关是滑动波导,可移动透镜或倾斜的镜子。通过选择特定的DFB激光器,控制温度以微调波长,以及调节微机械光学元件的位置,输出波长被设置为许多通信波长之一。 |
