New paper in OLEN analyzing the diffraction efficiency of stepped gratings in large phase modulation SLMs

OLENOur new publication is available in Optics & Lasers in Engineering, entitled Diffraction efficiency of stepped gratings using high phase-modulation spatial light modulators.

We study the diffraction efficiency of linear phase (blazed) diffraction gratings displayed onto SLMs that exhibit a large phase modulation range, reaching a maximum phase modulation of 8pi or 10pi radians. We analyse these effects for their important implications in the Nyquist limit for diffractive elements

The paper has been done in collaboration with our friends at San Diego State University.

New paper in OLEN with a technique to generate vector beams

OLENA 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.
