Abstract
A photonics package that incorporates a liquid crystal lens situated between a light source and a waveguide or output element of the package. The liquid crystal lens may focus or collimate light passing through it. This may be useful, for example, to focus light from a light source on or at an entry of a waveguide. Certain embodiments may include or incorporate routing or optical elements between the light source and the liquid crystal lens, and/or on a side of the lens opposite a side on which the light source is located.
