All-optical switching based on inverse Raman scattering in liquid-core optical fibers
(Georgia Institute of Technology, 2012-03)
We report on a new platform for all-optical switching based on inverse Raman scattering in liquids. Narrowband switching, which could be suitable for wavelength-division-multiplexed applications, is demonstrated using ...
Rapid, broadband two-photon-excited fluorescence spectroscopy and its application to red-emitting secondary reference compounds
(Georgia Institute of Technology, 2011-08)
We present a methodology for rapidly acquiring broadband two-photon absorption (2PA) spectra by means of a compact two-channel femtosecond fluorescence excitation apparatus. This technique is insensitive to differences in ...
A comprehensive analysis of the contributions to the nonlinear optical properties of thin Ag films
(Georgia Institute of Technology, 2010-06)
The nonlinear optical properties of 20 nm thick Ag films are investigated by time-resolved white- light continuum pump-probe experiments in both transmission and reflection mode. The dynamics of changes in permittivity Δε ...
Linear and nonlinear optical properties of Ag/Au bilayer thin films
(Georgia Institute of Technology, 2012-04)
The linear and nonlinear optical properties of Ag/Au bilayer metallic thin films with a total thickness of around 20 nm and with different Ag/Au mass-thickness ratios were studied. This study shows that the spectral ...
Nonlinear optical properties of induced transmission filters
(Georgia Institute of Technology, 2010-08)
The nonlinear optical (NLO) properties of induced transmission filters (ITFs) based on Ag are experimentally determined using white light continuum pump-probe measurements. The experimental results are supported using ...
