Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells

Advanced Optical Materials, EarlyView.
We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we

Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing

Advanced Optical Materials, EarlyView.
An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...

Computational Analysis of a GST‐Based Long‐Wave Infrared Microring Resonator on a ZnSe Platform as a Photonic Sensor

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 (GST)‐based microring resonator is designed and simulated on a ZnSe‐platform that operates in the long‐wave infrared (LWIR) wavelength of 8 μm. The structure demonstrates strong power confinement and high Q‐factor. GST resonator is used for gas and biosensing applications.
