Abstract

Large-angle light deflection is accomplished by diffraction from an optically induced index modulation created by the interference of two controlling light beams. The control beam wavelength is used to change the frequency of the transient grating and hence the resulting deflection angle. The Bragg condition is maintained over a wide range of deflection angles by the use of a novel optical system containing diffractive elements operating in real-time to tilt the diffracting structure. The results of a computer simulation and optimization program are presented together with experimental verification demonstrating 11.8° deflection from a 0.027 μm wavelength change.
