IR sensor sensitivity pushed into visible spectrum

Abstract:
XenICs, a spin-out from Belgian research lab IMEC, has used substrate thinning to push sensitivity in its infra-red sensors into the visible spectrum.

"Total wavelength area is now 0.4µm to 1.7µm," said XenICs. "This extended optical feature is based on the removal of the InP substrate from the thermoelectrically cooled InGaAs sensor array. Instead of 125µm in the standard layout, the new chip after removing the InP substrate is only 5µm thick."
