CMOS image sensor with micro-nano holes to improve NIR optical efficiency: micro-holes on top surface vs on bottom
E. Ponizovskaya Devine, Ahasan Ahamad, Ahmed Mayet +5
We study the nano- and micro-structures that increase the optical efficiency of the CMOS image pixels in visible and infrared. We consider the difference between the micro-holes at…
Single Micro-hole per Pixel for Thin Ge-on-Si Image Sensor with Enhanced Sensitivity upto 1700 nm
Ekaterina Ponizovskaya-Devine, Ahmed S. Mayet, Amita Rawat +5
We present a Ge-on_Si CMOS image sensor with backside illumination for the near-infrared electromagnetic waves, wavelengths range 300-1700nm, detection essential for optical sensor…
Enhanced quantum efficiency and reduction of reflection for MSM photodetectors with nano-structured surface
Ekaterina Ponizovskaya Devine, Yang Gao, Cesar Perez +4
The photon trapping nano-structures help to enhance quantum efficiency and reduce reflection for MSM photodetector that allows fast Si photodetectors at wavelength 800-950nm. The n…
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…
