Self-powered InAs nanowire detector arrays for extended-SWIR spectrometry at room temperature
Yang Yu, Wei Wen Wong, Zhe Li +16
Spectral sensing in the extended shortwave infrared (e-SWIR) is important for molecular analysis, infrared imaging, and machine vision, motivating the development of compact spectr…
Hyperdoped silicon photodetectors enable room-temperature computational SWIR imaging at 1550 nm
Xiaolong Liu, Sören Schäfer, Jinyuan Chen +8
Silicon's bandgap inherently restricts its photodetection to wavelengths below 1100 nm, necessitating the integration of costly III-V semiconductors for short-wave infrared applica…
High Pixel Resolution Visible to Extended Shortwave Infrared Single Pixel Imaging with a black Phosphorus-Molybdenum disulfide (bP-MoS2) photodiode
Seyed Saleh Mousavi Khaleghi, Jinyuan Chen, Sivacarendran Balendhran +5
High-resolution infrared imagers are currently more expensive than CMOS and CCD cameras, due to costly sensor arrays. Van der Waals (vdWs) materials present an opportunity for low-…
High Performance MoS2 Phototransistors Photogated by PN Junction
Seyed Saleh Mousavi Khaleghi, Jianyong Wei, Yumeng Liu +4
Photodetectors based on two-dimensional (2D) atomically thin semiconductors suffer from low light absorption, limiting their potential for practical applications. In this work, we…
Quantum Imaging Using Spatially Entangled Photon Pairs from a Nonlinear Metasurface
Jinyong Ma, Jinliang Ren, Jihua Zhang +4
Nonlinear metasurfaces with subwavelength thickness were recently established as versatile platforms for the enhanced and tailorable generation of entangled photon pairs. The small…
Metasurfaces for infrared multi-modal microscopy: phase contrast and bright field
Shaban B. Sulejman, Lukas Wesemann, Mikkaela McCormack +9
Different imaging modalities are used to extract the diverse information carried in an optical field. Two prominent modalities include bright field and phase contrast microscopy th…
