Goodrich's optical and space systems division (formerly Sensors Unlimited) introduces this near-infrared avalanche photodiode for geiger or linear mode single-photon counting
Goodrich announces a unique indium gallium arsenide/indium phosphide (InGaAs/ InP) near-infrared avalanche photodiode (APD) designed for single-photon counting at wavelengths of 0.9 to 1.6 microns.
The new SU055-GM-APD-FO offers an extremely low dark current with high responsivity, making it ideal for Geiger mode single-photon counting.
It is also capable of high-gain linear mode single-photon counting with a quantum efficiency greater than 70 percent.
Featuring ultra low-noise analogue optical detection up to approximately 1GHz, Goodrich's new device incorporates a high-performance APD chip, a thermoelectric cooler, a thermistor and optical fibre coupling optics into a compact and robust, hermetic package.
The standard module comes with one meter of 50-micron core, multi-mode fibre with an FC connector for easy integration.
Optional single-mode fibre pigtail is also available.
Other applications for the new near-infrared APD include quantum cryptography, optical time domain reflectometry, near-infrared Raman spectroscopy, biomedical NIR spectroscopy, time-resolved emission detection for failure analysis and singlet oxygen detection.
The high dynamic range device is manufactured by a business unit of Goodrich's optical and space systems division based in Princeton, NJ, (formerly Sensors Unlimited).
Goodrich has pioneered the design and production of shortwave infrared components, cameras and systems utilising advanced InGaAs imaging technology for industrial, commercial, military, agricultural and biomedical markets.
