Method of coupling radiation in an infrared detector, and an arrangement herefor
Jan Andersson,Lennart Lundqvist +1 more
TL;DR: In this paper, a two-dimensional crossed grating (6), a so-called 2-D grating, is constructed on the top of the detector mesa of the infrared detector on the side opposite the surface through which incident light (5) enters the detector.

Long-wavelength quantum-well infrared detectors based on intersubband transitions in InGaAs/InP quantum wells
TL;DR: In this article, it was shown that very high current responsivities and high gain are obtained when approaching detector voltages close to -8.5 V, which is explained by carrier impact excitation of electrons from the QW ground state to the excited extended state.
