The frequency of DFB LD was driven and controlled through such technology as constant current, temperature control in active area, wavelength lock and etc.
该方案通过采用恒流源、有源区温度控制以及波长锁定等技术方法来实现DFBLD的稳频驱动及控制。
Area which was floor steady state temperature area had weak effect by leakage, the temperature was mainly controlled by the original floor temperature field.
受泄漏影响较弱区域为3区地板稳态温度区，其温度主要由原始地板温度场控制。
