Three-Photon Absorption Spectra and Bandgap Scaling in Direct-Gap Semiconductors
Sepehr Benis, Claudiu M. Cirloganu, Nicholas Cox +11
This paper presents three-photon absorption (3PA) measurement results for nine direct-gap semiconductors, including full 3PA spectra for ZnSe, ZnS, and GaAs. These results, along w…

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$_{…
