Photodetector is a hybrid twelve-channel device with a photocathode sensitive in NIR range.
The photocathode with drawing electrical field, based on InP/InGaAs structure provides high sensitivity in range of 950 ÷ 1650 nm.
A silicon photodiode linear structure is used as the anode, back-side illuminated by photoelectrons with an energy of several keV, with a front of the impulse response of the diodes less than 10 ns. Sensitivity of any channel is more than 1 A/W.
Application:
– airborne systems;
̵ laser locators;
̵ measurement of laser pulses in the IR range.
