介绍了一种集成化、紧凑型、低成本、无热的波长锁定器。它使用一种新型标准具材料--白钨矿，与商用熔融二氧化硅储物柜相比，可将环境温度敏感度降低一个数量级以上。给出了温度不敏感标准具的热光特性。结果表明，采用基于施奈特标准具的鉴别器的器件的频率稳定性显示，在外壳和激光温度的较大变化下，光学频率漂移低于1 GHz。这一使能技术促进了未来小型化、低功耗、多通道激光光源的发展。
A package-integrated, compact, low-cost, athermal wavelength locker is introduced. It uses a novel etalon material, Schnaelite, to reduce environmental temperature sensitivity well over an order of magnitude compared to commercially available fused silica based lockers. Thermo-optical properties of temperature insensitive etalons are presented. Results demonstrating frequency stability of devices incorporating Schnaelite etalon based discriminators show optical frequency shifts below 1 GHz for large changes in case and laser temperature. This enabling technology promotes future small form-factor, low power consumption, multichannel laser sources.
