Impact of duty cycle and nano-grating height on the light absorption of plasmonics-based MSM photodetectors

Impact of duty cycle and nano-grating height on the light absorption of plasmonics-based MSM photodetectors

We use finite difference time-domain (FDTD) method to calculate the light absorption enhancement of nano-grating assisted metal-semiconductor-metal photo-detectors (MSM-PDs). The simulated results show that the light absorption enhancement of nano-grating assisted MSM-PD is ~9-times better than conv...

Zusammenfassung:We use finite difference time-domain (FDTD) method to calculate the light absorption enhancement of nano-grating assisted metal-semiconductor-metal photo-detectors (MSM-PDs). The simulated results show that the light absorption enhancement of nano-grating assisted MSM-PD is ~9-times better than conventional MSM-PD.
