WebAug 1, 2024 · The grating period and length were defined to be 535.44 nm and 15 mm, respectively. The optimal writing conditions for an FBG centered in the core were found to be 60 nJ of pulse energy, 50 μm/s of scanning velocity, fiber tension of 1 N, and a writing beam polarization aligned with the scanning direction of the fiber, [29]. Weband direct-view displays, polarized beam splitting devices, multiplexing, and polarization dispersion applications. In this paper we investigate the structure of a number of gratings formed using polarization holography for liquid-crystal alignment. The field of patterning surface alignment layers for liq-uid crystals is vast.
