Demonstration of polarization-insensitive spatial light modulation using a single polarization-sensitive spatial light modulator. [PDF]
Sci Rep, 2015 AbstractWe present a simple configuration incorporating a single polarization-sensitive phase-only liquid crystal spatial light modulator (LC-SLM) to facilitate polarization-insensitive spatial light modulation. The polarization-insensitive configuration is formed by a polarization beam splitter (PBS), a polarization-sensitive phase-only LC-SLM, a half-

Patterned Rydberg excitation and ionization with a spatial light modulator [PDF]
New Journal of Physics, 2015 We demonstrate the ability to excite atoms at well-defined, programmable locations in a magneto-optical trap, either to the continuum (ionization), or to a Rydberg state.

White light wavefront control with a spatial light modulator
Optics Express, 2014 Spatial light modulators are ubiquitous tools for wavefront control and laser beam shaping but have traditionally been used with monochromatic sources due to the inherent wavelength dependence of the calibration process and subsequent phase manipulation.

Establishment of the fundamental phase-to-polarization link in classical optics
Fundamental Research, 2021 Vector polarization induced by a change in the scalar phase is far beyond our understanding of the relationship between polarization and phase in classical optics due to the entanglement of the inherent polarized modes of light beams.
