Testing Laser Diodes
NI recommends that you calibrate the responsivity and dark current of the external photodetector (ePD) before testing an LD and fill in the values of the PD responsivity and PD dark current parameters
The fundamental test of a laser diode is a Light-Current-Voltage (LIV) curve, which simultaneously measures the electrical and optical output power characteristics of the device. This test is primaril...
