Interpretable inverse-designed cavity for on-chip nonlinear and quantum optics
Zhetao Jia, Wayesh Qarony, Jagang Park +9
Inverse design is a powerful tool in wave-physics and in particular in photonics for compact, high-performance devices. To date, applications have mostly been limited to linear sys…
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…
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…
Single Microhole per Pixel in CMOS Image Sensor with Enhanced Optical Sensitivity in Near-Infrared
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…
Excitation Wavelength Dependent Reversible Photoluminescence Peak in Iodide Perovskites
Wayesh Qarony, Mohammad Kamal Hossain, Mohammad Ismail Hossain +8
Halide perovskites have indisputably exceptional optical and electronic properties, which are attractive for next-generation optoelectronic device technologies. We report on a reve…
