Nondegenerate Two-Photon Absorption in GaAs/AlGaAs Multiple Quantum Well Waveguides
Nicholas Cox, Junxiong Wei, Himansu Pattanaik +4
We present femtosecond pump-probe measurements of the nondegenerate (1960nm excitation and 1176--1326nm probe) two-photon absorption spectra of 8 nm GaAs/12nm Al$_{…
Enhancement of Two-photon Absorption in Quantum Wells for Extremely Nondegenerate Photon Pairs
Himansu S. Pattanaik, Matthew Reichert, Jacob B. Khurgin +2
We recently demonstrated orders of magnitude enhancement of two-photon absorption (2PA) in direct gap semiconductors due to intermediate state resonance enhancement for photons of…
3-D IR imaging with uncooled GaN photodiodes using nondegenerate two-photon absorption
Himansu S. Pattanaik, Matthew Reichert, David J. Hagan +1
We utilize the recently demonstrated orders of magnitude enhancement of extremely nondegenerate two-photon absorption in direct-gap semiconductor photodiodes to perform scanned ima…
