Measurement of complex Χ(3) using degenerate four-wave mixing with an imaged 2-D phase grating
(Georgia Institute of Technology, 2006-09)
We present a simple optical arrangement for phase sensitive detection of degenerate four-wave mixing (DFWM) to characterize the real and imaginary parts of c(3) using an imaged 2-D phase grating. Phase sensitive coherent ...
Quantum-chemical investigation of second-order nonlinear optical chromophores: Comparison of strong nitrile-based acceptor end groups and role of auxiliary donors and acceptors
(Georgia Institute of Technology, 2006-01)
We report a detailed quantum-chemical investigation of donor-acceptor substituted dipolar nonlinear optical chromophores incorporating the 4-(dimethylamino)phenyl donor end group and a variety of strong heterocyclic acceptor ...
