Description | This work examined InAs optical detectors that used internal amplification - so-called InAs avalanche photodiodes. These avalanche photodiodes are unique in that the operate at wavelengths up to 3300nm, far beyond most commercially-available devices. They are also capable of operating using minimal device cooling. In this work we used the diodes to detect small numbers of photons, as well as in distance measurement by measurement of light transit time, all at long operational wavelength. |
Exploitation Route | The work is being supported via the EPSRC Hub in Quantum Enhanced Imaging, and yielding much improved results, building on the work of the original project. |
