Study on the Red Light Optical Photodetector for Short Distance Optical Fiber Communication Systems
Red light is usually used as optical signal source in short distance optical fiber communication systems.Therefore,it is im-portant to study the organic photodetector (OPD) for red light.The red light OPDs based on CuPc/C60 plane heterojunction structure inserted NPB as anode buffer layer were successfully prepared and the results were compared with the ones using OPDs with no buffer layer,It was shown that the devices with NPB anode buffer layer can enhance the performance of OPDs obviously.
