用时域有限差分法计算了金属-半导体-金属光电探测器(MSM-PD)的光传输效率。在设计波长下，利用纳米光栅耦合表面等离子体共振可以增强MSM PDs的吸收。模拟结果表明，纳米光栅辅助的MSM-PD的光吸收增强效果是常规MSM-PD的9倍。
This paper presents the light transmission efficiency of metal–semiconductor–metal photo-detectors (MSM-PDs) using finite difference time-domain method. The absorption of MSM PDs can be enhanced with the aid of nano-grating coupled surface plasmon resonances at the design wavelength. The simulated results show that the light absorption enhancement of nano-grating assisted MSM-PD is9-times better than the conventional MSM-PD.
