Wavefront shaping: plane waves out of a point source
2007 (English)In: Proceedings of the Comsol users conference, 2007, 761-764 p.Conference paper (Other academic)
Using finite element method (FEM) implemented in Comsol Multiphysics simulation package, we present a model of beam shaper that converts spherical waves into one or two plane waves as a function of wavelength. Thus, the device can realize both wavefront shaping and beam splitting in only one structure. Comparing with different methods already presented, we introduce a solution for a smaller, simpler, and easier to manufacture device. We demonstrate a wavefront shaper using a microstructure of 8 x 8 μm size with commercially available material. We also discuss fabrication methods suitable for implementing the SU-8 polymer in the device.
