Achieving higher photoabsorption than group III-V semiconductors in silicon using photon-trapping surface structures
Wayesh Qarony, Ahmed S. Mayet, Ekaterina Ponizovskaya Devine +8
The photosensitivity of silicon is inherently very low in the visible electromagnetic spectrum, and it drops rapidly beyond 800 nm in near-infrared wavelengths. Herein, we have exp…
Optimizing the light penetration depth in APDs and SPADs for high gain-bandwidth and ultra-wide spectral response
Ahasan Ahamed, Cesar Bartolo-Perez, Ahmed Sulaiman Mayet +7
Controlling light penetration depth in Avalanche Photodiodes (APDs) and Single Photon Avalanche Diodes (SPADs) play a major role in achieving high multiplication gain by delivering…
Reconstruction-based spectroscopy using CMOS image sensors with random photon-trapping nanostructure per sensor
Ahasan Ahamed, Cesar Bartolo-Perez, Ahmed Sulaiman Mayet +4
Optical spectrometers are widely used scientific equipment with many applications involving material characterization, chemical analysis, disease diagnostics, surveillance, etc. Em…

E. Ponizovskaya Devine, Wayesh Qarony, Ahasan Ahamed +7
Silicon photodiode based CMOS sensors with backside-illumination for 300 to 1000 nm wavelength range were studied. We showed that a single hole in the photodiode increases the opti…
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…
