Jy. Duboz et al., MONOLITHIC SPECTROMETER BASED ON INTERSUBBAND TRANSITIONS IN QUANTUM-WELLS, IEEE journal of quantum electronics, 30(7), 1994, pp. 1507-1510
We present a new device based on the association of a quantum-well inf
rared photodetector and an asymmetric quantum-well infrared modulator
in a three-terminal monolithic structure. This device is shown to allo
w the spectral analysis of an infrared signal. A large tunability and
a constant responsivity make this device an ideal candidate for a soli
d-state infrared spectrometer.
