摘要 | A multi-wavelength laser array where each element can be individually heated for fine tuning. The wavelength of the array can be coarsely tuned by selecting one laser of a particular wavelength for the array, and then applying a heating current to fine-tune the wavelength. The lasers can be phase shifted DFBs for high single-mode yield. The heating can be performed monolithic to the device by passing current longitudinally through the p-type stripe, while the injection current passes vertically through the stripe. Alternatively an adjacent laser to the one selected can be activated, though not fiber coupled, such that the thermal load is sufficient to tune the selected laser. Thin film heaters placed on top or adjacent to the cavity can also be used. To minimize continuous power consumption, the on-chip heater can be used initially to tune the laser while the TE cooler responds on a slower time scale. |
其他摘要 | 一种多波长激光器阵列,每个元件可以单独加热以进行微调。通过为阵列选择特定波长的一个激光器,然后施加加热电流来微调波长,可以粗略地调谐阵列的波长。激光器可以是相移DFB,以实现高单模产率。通过使电流纵向穿过p型条带,同时注入电流垂直穿过条带,可以对器件进行单片加热。或者,可以激活所选择的激光器的相邻激光器,但不是光纤耦合的,使得热负载足以调谐所选择的激光器。也可以使用放置在腔体顶部或附近的薄膜加热器。为了最大限度地降低连续功耗,片上加热器最初可用于调谐激光器,而TE冷却器则在较慢的时间范围内响应。 |
