Abstract:
This study demonstrates a novel tunable grating based on a stressed liquid crystal (SLC) film. This device can be modulated by shearing a length or applying an AC voltage to tune the intensity and polarization of diffracted beams. The device capable of tuning the intensity and/or polarization of diffracted beams is essential to various optical systems. Thus, SLC gratings have potential for practical applications.
