Abstract
A liquid crystal (LC) beam steerer includes a waveguide apparatus with a waveguide having a high-index core in contact with a variable-index liquid crystal (LC) cladding, wherein a voltage applied to the LC cladding is effective to steer a beam of light passing through the high-index core. Measuring the bulk birefringence and/or the capacitance characteristics of the LC can facilitate beam steering.
