Quantum efficiency enhancement of mid infrared photodetectors with photon trapping micro-structures
Ekaterina Ponizovskaya Devine, Hilal Cansizoglu, Yang Gao +5
The study proposes to use the photon trapping micro-structures to enhance quantum efficiency of the mid infrared photodetectors. The nanostructure that is consist of micro holes re…

Optimization of light trapping micro-hole structure for high-speed high-efficiency silicon photodiodes
Ekaterina Ponizovskaya Devine, Hilal Cansizoglu, Yang Gao +8
We optimized micro-holes in a thin slab for fast Si photodetectors at wavelength 800-950nm. Lateral modes are shown to be responsible for the effective light trapping. Small disord…
