Nonvolatile Phase-Only Transmissive Spatial Light
Our work presents zero-static power transmissive phase-only SLMs, enabled by electrically controlled low-loss PCMs and individual meta-molecule
Spatial Light Modulation Principles
Correction is achieved using two spatial light modulators in series—the first performs amplitude modulation, while the second compensates for phase distortion, ensuring consistent optical elements
Spatial light modulators for phase-only modulation
For practical purposes, we have developed a nonpixelized, electrically addressed spatial light modulator such as electron beam addressed spatial light modulator (EBSLM) and LCD coupled PAL-SLM. We

Our work presents zero-static power transmissive phase-only SLMs, enabled by electrically controlled low-loss PCMs and individual meta-molecule addressable metasurfaces.
Shaping the Amplitude and Phase of Laser Beams by
We show how to encode the complex field of laser beams by using a single phase element. A common-path interferometer is employed to mix the
Arbitrary manipulation of spatial amplitude and phase using phase
In this paper, we propose an alternative simple method to arbitrarily manipulate the amplitude and phase of the incoming light beam with two phase-only SLMs without using any phase...
Fast and light-efficient wavefront shaping with a MEMS phase-only
In this work we test a new type of SLM, known as a phase-only light modulator (PLM), that blends the high efficiency of liquid crystal SLMs with the fast switching rates of binary digital micro
Nonvolatile Phase-Only Transmissive Spatial Light Modulator with
Finally, we demonstrate the device''s functionality as a fully configurable spatial light modulator by independently control-ling each meta-molecule to locally impart phase shifts and to manipulate the

We show how to encode the complex field of laser beams by using a single phase element. A common-path interferometer is employed to mix the phase information displayed into a
Simple and fast calibration method for phase-only spatial light
In practice, our calibration method works well with as few as 18 interferograms, which can be quickly acquired without concern for phase drift. We detail the calibration procedure and
