Abstract
In this paper we have demonstrated a wavelength tuning scheme using a twisted nematic liquid crystal based LCTV operated in an amplitude coupled binary phase mode for three wave mixing devices. A cosine chirp that is written on the LCTV by electrically addressing its pixels through a personal computer, functions as a programmable spherical lens. Deflection of the input beam is achieved by introducing tilt aberration on the lens. A spot resolution of less than 1.65 arcsec, and a steering range of 2 degrees at a wavelength of 632.8 nm were achieved by continuously varying the tilt coefficient of the lens. The potential advantages of this scheme are speed, compactness, operational ease, and power consumption.
