ABSTRACT
We report on a two-photon detector based on resonantly enhanced nonlinear absorption between subbands in InGaAs/InAlAs quantum wells and demonstrate its use as a quadratic autocorrelator for midinfrared pulses. Modified device design allows for device operation at room temperature, which is crucial for applications in practical systems.

    We report observation of transverse electric (TE) dominant intersubband absorption in Si-doped GaInAsN/GaAs multiple-quantum-well structures. The TE dominant absorption is believed to be caused by the incorporation of nitrogen and the associated nitrogen state. When the confinement is strong in...

    Characteristics of In(Ga)As quantum ring infrared photodetectors (QRIPs) were investigated under normal incidence configuration.
