Metal nano-grating optimization for higher responsivity plasmonic-based gaas metal-semiconductor-metal photodetector
Karar, Ayman; Tan, Chee Leong; Alameh, Kamal; Lee, Yong Tak; Karouta, Fouad
Description
To improve the responsivity of the metal semiconductor metal photodetector (MSM-PD), we propose and demonstrate the use of sub-wavelength slits in conjunction with nano-structured the metal fingers that enhance the light transmission through plasmonic effects. A 4-finger plasmonics-based GaAs MSM-PD structure is optimized geometrically using a 2-D Finite Difference Domain (FDTD) method and developed, leading to more than 7-times enhancement in photocurrent in comparison with the conventional...[Show more]
