摘要:
The present invention provides a method for adjusting a diffraction grating to changes in ambient conditions. The method includes writing a diffraction grating in the photorefractive waveguide with a laser, measuring spectral characteristics of the diffraction grating, and allowing the diffraction grating to self-write from interference between a forward beam and a Fresnel reflection, such that the diffraction grating is adjusted for changes in ambient conditions.
