Title:
MIDDLE-INFRARED VOLUMETRIC BRAGG GRATING BASED ON ALKALIHALIDE COLOR CENTER CRYSTALS
Document Type and Number:
WIPO Patent Application WO/2013/106867
Kind Code:
A3
Abstract:
Volumetric Bragg grating devices that operate in middle-infrared region of the spectrum and methods for producing such devices are described. Such a Volumetric Bragg grating device can be produced by forming a plurality of color centers within an alkali-halide crystal and selectively removing a subset of the plurality of color centers to produce variations in refractive index of the alkali-halide crystal in the middle-infrared spectral region and to thereby produce a volumetric Bragg grating that operates in middle-infrared spectral range.
