| titleOfInvention | A test device for a photodiode |
| abstract | The invention discloses a photodiode testing device, which includes an excitation module, including a light source assembly, a chopper, a focusing achromatic lens and a function generator; a signal collection module, including two signal channels, a processor and a The sample stage of the device to be tested, the two signal channels are spatially symmetrical along the device to be tested, and the two signal channels both include signal collection components. Aiming at the problem that the existing electroabsorption spectroscopy technology cannot measure the photodiode under the forward bias voltage, the test device of the photodiode of the present invention successfully avoids the photodiode electroluminescence to the test signal by introducing the balanced differential measurement into the signal collection module. Therefore, the electroabsorption spectroscopy measurement under the forward bias of the photodiode was successfully realized. It also provides an effective characterization method for studying the internal local electric field, built-in electric field and attenuation mechanism of active electroluminescent devices, and has important practical value. |
