Bragg grating and method of producing a bragg grating using an ultrafast laser |
摘要 |
A novel method and apparatus for varying the index of refraction of a material using an interference pattern is disclosed. The method and apparatus incorporate an ultra short duration pulse laser source. Electromagnetic radiation provided from the laser propagates to a diffractive element positioned in close proximity to the target material. The diffracted electromagnetic radiation forms an interference pattern, the peaks of which are sufficiently intense to cause a change in index of refraction.
