Abstract :
Surface plasmonic resonance has been proved to be an effective way for enhancing infrared photodetector performance. In this paper, we report the optimization of the plasmonic structures by numerical simulation and experimental verification. The mechanism of the high enhancement is also analyzed and discussed for different plasmonic structures.
