摘　　要：文章介绍了可调谐激光器的波长调节及稳定控制的设计方法,并通过试验验证了其可行性。该设计由温度控制、偏置电流控制及锁波电路3部分组成,温度控制粗调波长,偏置电流控制微调波长,而锁波电路主要是针对外界温度发生变化时提供反馈。它适用于温度控制型分布反馈式(DFB)可调谐激光器的外围电路设计。The design of wavelength tuning and stability control of tunable lasers is introduced and its feasibility verified by tests. The design scheme consists of temperature control, bias current control and wavelength locker circuits. The temperature control circuit is used for cursory tuning, the bias current circuit for fine tuning and the wavelength locker circuit for feedback of external temperature variations. It is applicable to the design of the driver circuit of the temperature control-based tunable DFB laser.
