Figure Lengend Snippet: a Experimental setup using a 795 nm VCSEL and a CMOS image sensor, with the WGP mounted on a rotational stage. b Schematic diagrams of the WGP and input polarization orientations at 0°, 45°, and 90°. c Transmitted images of the beam profiles for input polarization angles of 0°, 45°, and 90°, showing spatial variation in transmission intensity due to polarization-selective regions of the WGP. d Corresponding 1D intensity profiles extracted along the indicated direction (blue dotted line in c ) for each polarization angle, confirming spatial separation and modulation of polarization components
Article Snippet: Measurements were performed at polarization rotation angles of 0°, 45°, and 90° using a rotational mount (RSP1, Thorlabs).
Techniques: Transmission Assay
