High resolution multispectral spatial light modulators based on tunable Fabry-Perot nanocavities
Light: Science & Applications, 2022 A spatial light modulator is demonstrated based on Fabry-Perot nanocavity resonances, enabling micrometer-sized pixels and efficient full phase control at multiple wavelengths simultaneously, across the visible spectrum (including RGB colors).

Programmable unitary operations for orbital angular momentum encoded states
National Science Open, 2022 We have proposed and demonstrated a scalable and efficient scheme for programmable unitary operations in orbital angular momentum (OAM) domain. Based on matrix decomposition into diagonal and Fourier factors, arbitrary matrix operators can be implemented

Multi-spectral random illumination using a liquid crystal spatial light modulator
Journal of the European Optical Society-Rapid Publications, 2018 Background Using phase-only liquid crystal spatial light modulator (LC-SLM) to generate random illumination is always used in phase-retrieval and single pixel imaging as it have high energy efficiency.

Full-complex amplitude modulation with binary spatial light modulators [PDF]
Journal of the Optical Society of America A, 2011 Imperfections and nonrobust behavior of practical multilevel spatial light modulators (SLMs) degrade the performance of many proposed full-complex amplitude modulation schemes. We consider the use of more robust binary SLMs for this purpose. We propose a generic method, by which, out of K binary (or 1 bit) SLMs of size M×N, we effectively create a new ...

Patterned Rydberg excitation and ionization with a spatial light modulator
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.

Scattering of Sculpted Light in Intact Brain Tissue, with implications for Optogenetics
Scientific Reports, 2015 Optogenetics uses light to control and observe the activity of neurons, often using a focused laser beam. As brain tissue is a scattering medium, beams are distorted and spread with propagation through neural tissue and the beam’s degradation has ...

A low-voltage high-speed terahertz spatial light modulator using active metamaterial
APL Photonics, 2016 An all solid-state metamaterial based terahertz (THz) spatial light modulator (SLM) is presented which uses high mobility 2DEG to manipulate the metamaterial resonant frequency (0.45 THz) leading to terahertz wave modulation.

Scalable micromesh-digital spatial light modulators
Optics Express, 2015 Digital spatial light modulators (SLMs) with small pitch comparable to the wavelength of illuminating light and large physical dimension comparable to consumer displays are highly demanding for realizing realistic digital holography but are impractical due to various technical issues. Previously we proposed the way to overcome these hurdles by scalable
