Abstract

An upconverter is demonstrated for long-wave infrared (LWIR) detection in a wide wavelength range, which can be potentially used for LWIR spectroscopy. The LWIR signal is mixed with a 1064 nm laser beam in a silver gallium sulfide (AgGaS2) crystal using angle tuning for optimal phase-matching. This allows for efficient, high-speed detection of long-wave infrared signals using a standard silicon detector.
