Spatial Light Modulator Simulated Grating
To generate high-order and fractional-order vortex beams, a spatial light modulator was used to simulate a forked grating. This was performed to generate and isolate the desired vortex beams with the different orbital angular momentum (OAM) of l, and investigated their. The Grating Light Valve (GLV ®) is a high-performance spatial light modulator comprising a linear array of thousands of micro-ribbons anchored on the surface of a silicon chip. A common problem in these devices is the pixel crosstalk, also called the fringing field effect, which causes.
