Bragg grating made in optical waveguide |
摘要 |
A Bragg grating is made in an optical path composed of material exhibiting change in index when exposed to radiation of an actuating frequency by passing radiation from a source of such actuating frequency through a mask with periodic variation in transmission to expose the material of the path to a diffraction pattern.
