V. Ryzhii et al., THEORETICAL-STUDY OF AN INFRARED-TO-VISIBLE WAVELENGTH QUANTUM-WELL CONVERTER, Semiconductor science and technology, 10(9), 1995, pp. 1272-1276
A monolithic wavelength converter of long-wavelength infrared radiatio
n to short-length infrared or visible radiation based on a quantum-wel
l structure has been proposed and considered theoretically. The quantu
m-well converter utilizes intersubband electron transitions in the emi
tter quantum well. The threshold intensity of long-wavelength infrared
radiation necessary for laser generation is evaluated as a function o
f the structural and physical parameters of the device.
