New paper in OLEN with a technique to generate vector beams
A new publication of our team is available at the journal Optics & Lasers in Engineering, entitled Efficient on-axis engineering of optical vector modes.
In this work we present a method for the efficient experimental generation of arbitrary polarized vector beam modes. The optical system employs two LCOS-SLMs in a common path architecture, avoiding the use of beam-splitters.
We apply a recently proposed random technique to encode complex amplitude values. This encoding technique reconstructs the complex function on-axis, thus avoiding incorporating carrier phases. We demonstrate arbitrary scalar modes encoded onto orthogonal polarization components, whose superposition results in a vector beam mode.
