Abstract

A reflective Bragg grating (21) in the interior of an infrared transmitting glass fiber (15), and its method comprising the steps of:
producing first and second writing beams (11, 13) at the same wavelength;
orienting the first and second writing beams (11, 13) in parallel with respect to each other; crossing the first and second writing beams at a preselected angle with respect to each other to form an interference pattern at the intersection of the first and second writing beams (11, 13); positioning the infrared transmitting glass fiber (15) at the intersection of the first and second writing beams (11, 13) so that the interference pattern occurs along a portion of the length of the infrared transmitting glass fiber (15); and maintaining the infrared transmitting glass fiber (15) at the intersection of the first and second writing beams (11, 13) for a time sufficient to produce a Bragg grating (21) in the core and cladding of the infrared transmitting glass fiber (15).
