Fiber Bragg Gratings in Chalcogenide or Chalcohalid Based Infrared Optical Fibers.
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.
