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.
We present our group's recent research progresses of mid-infrared (mid-IR) surface emitting two-dimensional (2D) photonic crystal (PC) lasers via MBE-grown IV-VI group semiconductors on silicon substrates. The device design was based on a 2D micron-level honeycomb structure, in which complete photonic bandgaps will form in mid-IR region. For the initial demonstration, two intensive PC modulated mid-IR...
