Optical components to polarizing beam-splitter alignment

Abstract

Methods and apparatuses for aligning an optical waveguide with a polarizing beam-splitter(PBS) and for aligning a reflective lens with the PBS once it is aligned with the optical waveguide are described herein. The methods involve various optical techniques that allow for precise location and angular alignment between the respective components. By using the described techniques, misalignment may be mitigated thereby reducing image distortion and poor angular distribution of light and increasing light for beams that are coupled out of the optical waveguide.
