High-Flexibility Control of Structured Light with Combined Adaptive Optical Systems
Photonics, 2022 Combining the specific advantages of high-resolution liquid-crystal-on-silicon spatial light modulators (LCoS-SLMs) and reflective or refractive micro-electro-mechanical systems (MEMS) presents new prospects for the generation of structured light fields.

Rapid Generation of Light Beams Carrying Orbital Angular Momentum [PDF]
, 2013 We report a technique for encoding both amplitude and phase variations onto a laser beam using a single digital micro-mirror device (DMD). Using this technique, we generate Laguerre-Gaussian and vortex orbital-angular-momentum (OAM) modes, along with ...

Optimized generation of spatial qudits by using a pure phase spatial light modulator [PDF]
, 2014 We present a method for preparing arbitrary pure states of spatial qudits, namely, D-dimensional (D > 2) quantum systems carrying information in the transverse momentum and position of single photons.

Spatially incoherent off-axis Fourier holography without using spatial light modulator (SLM)
Optics Express, 2016 We present a spatially incoherent dual path Fourier holographic system. Conceptually it is similar to Fourier incoherent single channel holography (FISCH). Although our incoherent off-axis Fourier holographic (IOFH) system does not have the robustness of a single channel system, it has three advantages over FISCH, with two being quite obvious from ...

Theranostics, 2020 High speed imaging is pre-requisite for monitoring of dynamic processes in biological events. Here we report the development of a unique spatial light-modulated stimulated Raman scattering (SLM-SRS) microscopy that tailors the broadband excitation beam with sparse-sampling masks designed for rapid multiplexed vibrational imaging to monitor real-time ...

Encoding of arbitrary micrometric complex illumination patterns with reduced speckle [PDF]
, 2019 In nonlinear microscopy, phase-only spatial light modulators (SLMs) allow achieving simultaneous two-photon excitation and fluorescence emission from specific regionof-interests (ROIs). However, as iterative Fourier transform algorithms (IFTAs) can only

Quantum key distribution session with 16-dimensional photonic states [PDF]
, 2013 The secure transfer of information is an important problem in modern telecommunications. Quantum key distribution (QKD) provides a solution to this problem by using individual quantum systems to generate correlated bits between remote parties, that can ...

Spatial-Light-Modulator-Based Multichannel Data Transmission by Vortex Beams of Various Orders
Sensors, 2021 We report an atmospheric multichannel data transmission system with channel separation by vortex beams of various orders, including half-integer values. For the demultiplexing of the communication channels, a multichannel diffractive optical element (DOE)
