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…
Effective Third-Order Nonlinearities in Metallic Refractory Titanium Nitride Thin Films
Nathaniel Kinsey, Akbar Ali Sayed, Devon Courtwright +7
Nanophotonic devices offer an unprecedented ability to concentrate light into small volumes which can greatly increase nonlinear effects. However, traditional plasmonic materials s…
