| Abstract: | Response characteristic of photodetector,which is caused by polarization state of incident light,is analyzed.The calculation formula of polarizationdependent sensitivity is deduced,and an InGaAs detector is fabricated for the experimental test.In order to test the polarizationdependent sensitivity of photodetector,an experimental system is established,and the polarizationdependent sensitivity of the InGaAs detector is measured.The results indicate that the experimental system has a good stability and the po... |
