An image intensifier comprising:
- a quantum well infrared photodetector (QWIP) configured to receive photons to photoexcite carriers out of a localized quantum state;
- and
- a light emitting diode (LED), wherein the photoexcited carriers control the LED.
A night-vision system including a circuit comprising:
- a photothyristor;
- a transistor;
- and
- a gate voltage source,
- wherein the gate voltage source biases a gate of the transistor and the photothyristor serves as an active load for the transistor.
