AI-Augmented Photon-Trapping Spectrometer-on-a-Chip on Silicon Platform with Extended Near-Infrared Sensitivity
Ahasan Ahamed, Htet Myat, Amita Rawat +2
We present a compact, noise-resilient reconstructive spectrometer-on-a-chip that achieves high-resolution hyperspectral imaging across an extended near-infrared (NIR) range up to 1…
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…
Optimization of CMOS image sensors with single photon-trapping hole per pixel for enhanced sensitivity in near-infrared
E. Ponizovskaya Devine, Ahasan Ahamed, Ahmed S. Mayet +7
The optimization of silicon photodiode-based CMOS sensors with backside-illumination for 300-1000 nm wavelength range was studied. It was demonstrated that a single hole on a photo…
