资料介绍

为了保持光收发模块发射光波长的稳定,采用半导体热电制冷器对模块中激光器温度进行控制的方法,设计了以热电制冷器为核心的具有高采样精度和快速响应速度的温度控制电路,并进行了理论分析和实验验证,取得了使用本电路的样品模块在应用温度范围内的发射波长变化数据。结果表明,优化后的热电制冷器温控电路具有良好的性能,能够快速准确地控制激光器温度,将发射光波长的变化精确锁定在20pm范围之内。设计完全满足实际应用要求。

In order to maintain the stability of the emission wavelength of an optical transceiver, a thermoelectric cooler was adopted to control the temperature in the transceiver. A temperature control circuit was designed with high sampling precision and fast response speed. Through theoretical analysis and experimental verification, the dependence of emission wavelength on the temperature was obtained in the application temperature range. The results show that the optimized temperature control circuit of thermoelectric cooler has good performance, which can control the temperature of the laser accurately and quickly and lock the emission wavelength within 20pm change range. The design meets the requirements of practical applications fully.
