Using a spatial light modulator (SLM) as a diffraction grating. The parts shown in (a) replace the transmission grating and rotating linear polarizer shown in Fig. 5.
In this article, we will explain how to model and simulate a diffraction grating with spatial variation using the LSWM plugin. The basic principle is to define a grid of points, each labeled with an i...

With modularized hardware and polarized laser modulation, we developed a nanoscale super-resolution structured illumination microscope (SR-SIM) imaging

For certain applications, such as augmented reality glasses, it is necessary to spatially vary the gratings along specific directions. In this article, we will explain
Abstract The diffraction characteristics of orthogonal gratings with variable duty cycles and phase modulation depths are analyzed by using a spatial light modulator.
DMD works by tilting the micromirrors between two states, sending the light in two directions. When the mirrors are in one state, the light is directed
GAEA-2.1 Phase Only LCOS-SLM The GAEA-2.1 Spatial Light Modulator is the highest resolution SLM on the market with extremely small pixel pitch.
Structured illumination in total internal reflection fluorescence microscopy using a spatial light modulator Opt Lett, 33 (14) (2008), pp. 1629 - 1631, 10.1364/OL.33.001629
This is the same as what we realized using our phasor model of the grating light modulator, but now we are in a position to get a more complete picture of how the light is distributed between diffraction
Meanwhile, the influences of the duty cycle and phase modulation depth on the diffraction characteristics of the orthogonal grating are discussed. The simulation

We present a general approach for optimizing the diffraction efficiency of a phase-type spatial light modulator (SLM). While the SLM displays a one-dimensional phase grating, the phase shift of one

In this work, we compare different methods for implementing a triplicator, a phase grating that generates three equi-intense diffraction orders. The design with optimal efficiency features a continuous phase

While applying a transverse oscillating magnetic field can mitigate low-frequency noise 11, pump light fluctuations near the modulation frequency remain the dominant limitation on sensitivity.
This allows operating phase-only diffractive optical elements in the second harmonic diffraction order, instead of in the usual first diffraction order. This type of implementation shows

In this work, we propose a parallel uncoupled spatial frequency modulation structure for multi-wavelength compatible, single-shot full-Stokes imaging. This is achieved by integrating a 2D
In this work we analyze diffraction gratings displayed on a pixelated spatial light modulator (SLM) at its spatial resolution limit (Nyquist limit) i.e., with largest diffraction angle, where the binary phase profile
Bragg gratings are reflecting structures with a periodic refractive index modulation. They are contained in dielectric mirrors and in some fiber devices.
