    Abstract: A solid state photonics circuit having a liquid crystal (LC) layer for beam steering. The LC layer can provide tuning of an array of waveguides by controlling the application of voltage to the liquid crystal. The application of voltage to the liquid crystal can be controlled to perform beam steering with the light signal based on different tuning in each of the waveguides of the array. The waveguides are disposed in a substrate having an oxide or other insulating layer with an opening. The opening in the oxide layer exposes a portion of a path of the array of waveguides. The waveguides are exposed to the liquid crystal through the oxide opening, which allows the voltage changes to the liquid crystal to tune the optical signals in the waveguides.
