Abstract

Poling nonlinear optical materials using light is reported. The new method, which combines a light- and an electrical-field effect and is effective on glassy solid-state materials, could in future be integrated into standard lithographic technology to produce, for example, nonlinear optical waveguides by irradiating through a mask when the electric field is switched on.
