Very few nonlinear optical materials are actually useful for high throughput all-optical devices. However, AlGaAs does satisfy all of the nonlinear optical figures of merit when used with photons of energy less than one half the semiconductor bandgap. Here we review our measurements of the pertinent nonlinear coefficients in waveguides and various device applications to all-optical switching in the communications band around 1550 nm.

A novel dmit2- salt: (hexadecyltrimethylammonium)bis(4,5-dithiolato-1,3-dithiole-2-thione)copper, abbreviated as HTCu , is synthesized and characterized for third-order optical nonlinearity by Z-scan technique at a wavelength of 1064 nm with laser duration of 30 ps. Z-scan spectra reveal a negative Kerr coefficient at 1064 nm and no nonlinear absorption was observed under this condition. The nonlinear refraction coefficient n2 and the second hyperpolarizability γ have been determined to be -1.51 × 10-11 and 1.36 × 10-30 esu , respectively, suggesting HTCu is a promising material for all-optical switching.
