Abstract:

A reflective Bragg grating in the interior of an infrared transmitting glass fiber, and a method for fabricating such reflective Bragg grating in the interior of the infrared transmitting glass fiber is disclosed. The method comprises the steps of producing first and second writing beams at the same wavelength orienting the first and second writing beams 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 positioning the infrared transmitting glass fiber at the intersection of the first and second writing beams so that the interference pattern occurs along a portion of the length of the infrared transmitting glass fiber and maintaining the infrared transmitting glass fiber at the intersection of the first and second writing beams for a time 7 sufficient to produce a Bragg grating in the core and cladding of the infrared transmitting glass fiber.
