Paper Abstract

Studies have been carried out across the visible on liquid crystal electro-optic (EO) and nonlinear optical devices. Two geometries were studied, a variable birefringence filter (VBF) and a Fabry Perot (FP) etalon, with a view to using them as (1) EO modulators and (2) EO tunable filters. Restrictions on device design and performance imposed by LC technology are analyzed and discussed. It is shown that for modulators the VBF yields better performance characteristics when employing LC technology, whereas for tunable filters the FP etalon geometry offers advantages. A hybrid spacer layer FP device and a double element VBF, designed to improve the wavelength selectivity of tunable filters, are described. Finally, results on bistable switching in the FP etalon are presented.
