Abstract:
Provided is an optical waveguide with an inscribed Bragg grating, where the Bragg grating is stable at high temperature, has low scattering loss and high reflectivity. Also provided is a method for inscribing a Bragg grating in an optical waveguide, the method comprising irradiating the optical waveguide with electromagnetic radiation from an ultrashort pulse duration laser of sufficient intensity to cause a permanent change in an index of refraction within a core of the optical waveguide, where the irradiating step is terminated prior to erasure of a Bragg resonance, and heating the optical waveguide to a temperature and for a duration sufficient to substantially remove a non-permanent grating formed in the optical waveguide by the irradiating step.

Claim (Index 2):
The method according to  claim 1 , which further comprises a step of:\n providing a diffractive optical element which, when exposed to the ultrashort laser pulse, creates an interference pattern on the optical waveguide, wherein the irradiation step comprises irradiating a surface of the diffractive optical element with the electromagnetic radiation, the electromagnetic radiation incident on the optical waveguide from the diffractive optical element being sufficiently intense to cause the permanent change in index of refraction in the core of the optical waveguide.
