Avalanche Photodetectors with Photon Trapping Structures for Biomedical Imaging Applications
Cesar Bartolo-Perez, Soroush Ghandiparsi, Ahmed S. Mayet +8
Enhancing photon detection efficiency and time resolution in photodetectors in the entire visible range is critical to improve the image quality of time-of-flight (TOF)-based imagi…
Maximizing absorption in photon trapping ultra-fast silicon photodetectors
Cesar Bartolo-Perez, Wayesh Qarony, Soroush Ghandiparsi +9
Silicon photodetectors operating at near-infrared wavelengths with high-speed and high sensitivity are becoming critical for emerging applications, such as Light Detection and Rang…
Up-conversion single-photon detectors based on integrated periodically poled lithium niobate waveguides
Fei Ma, Long-Yue Liang, Jiu-Peng Chen +6
We demonstrate up-conversion single-photon detectors based on integrated periodically poled lithium niobate waveguides, which incorporate two mode filters and a directional coupler…
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…
