The accelerating b-in and screening method of processing 1 310 nm InGaAsP of laser diodes (LDs)is introduced. It is confirmed that the theory of b-in and screening is based on the second derivative minimum of b-in curve, and the new testing method has been given, that is automatic current control (ACC) b-in and automatic power control (APC) testing. This avoidably bring the errors of testing in only ACC or APC method, which need to monitor and control or test LDs power change by photo-detector (PD) at high temperature, and LDs or PDs must be into the same environment (PD will be b-in at the same time). Through the experiment, the accelerating b-in and screening condition of the devices has been confirmed: ACC, 200 mA,100 ℃, 8 h. This raise work efficiency 12 times than Bellcore standard and save testing fee.
