Liquid Phase Epitaxial Indium-Gallium-Arsenide - Phosphide Avalanche Photodiodes for Near-Infrared Detection
… of InGaAsP/InP avalanche photodiodes for near-infrared detection is described in detail. Particular material requirements which must be satisfied for these devices are considered and the special techniques involved in the use of liquid phase epitaxy which have been developed for preparing …

Analysis of Near-Infrared Phase Effects on Biometric Iris Data
… potential iris scan data variations from near infrared waves derived from fluorescent illumination. Prior studies of iris data variances from infrared wave interference of halogen, incandescent, and sunlight with iris cameras suggest that similar changes may exist under near infrared …

New Fluorescence Sensors for Critical Materials
… that matter. This research shows real-time detection of minerals of significance using ‘novel’ fluorescence sensing through three regimes that are poorly covered in the existing literature: 1. Visible-light excitation and near infrared emission 2. “Cryogenic” fluorescence 3. Upconversion …

Studies on Optically Induced DC-Voltage in Thin Film Structures
… ranging from energy conversion to photodetection. However, there are still many challenges to reach high conversion efficiency and broad spectral coverage. Overall, photodetection through conventional procedures is based on light absorption by a material with a matching bandgap. This …
