On-the-fly writing of a long grating phase mask

Optical Engineering, 2011
A method is demonstrated for writing long grating phase masks, which can be used for patterning large-area (square meter size) submicron-period gratings. The method consist of illuminating a small area transmission grating phase mask by a continous wave transverse-electric-polarized collimated laser beam under the −1st order Littrow mounting to define ...

Interferometric characterization of phase masks

Applied Optics, 2003
We demonstrate a novel interferometric technique for highly accurate characterization of phase masks used in optical fiber grating fabrication. The principle of the measurement scheme is based on the analysis of the interference pattern formed between the first- and zero-order beams transmitted through or reflected from the grating under test.

Photorefractive phase mask

SPIE Proceedings, 2001
We propose and demonstrate a new method to fabricate volume phase mask in LiNbO 3 :Fe crystal by photorefractive effect, for the first time to our knowledge. First, we image an amplitude mask with corresponding intensity distribution at the incident face of a photorefractive LiNbO 3 :Fe crystal.
