New paper in Optical Engineering about the generation of vector beams with a new optical processor
Our last paper published in Optical Engineering is entitled Vector beams generated with a Fourier transform processor with geometric phase grating.
In this work we present a new method to generate vector beams with a 4f polarization Fourier filtering system that combines a spatial light modulator (SLM) at the input plane and a geometric phase polarization diffraction grating (PDG) at the output plane. This new systems presents advantages in terms of light efficiency and flexibility compared to other previous approaches.
The work has been done in collaboration with Prof. Jeffrey A. Davis and Prof. Don M. Cottrell from the Department of Physics at San Diego State University.
