摘要： An integrated planar Bragg grating is fabricated by depositing layers of material onto a negative expansion substrate to form a waveguide, which is held in mechanical tension with the substrate. A Bragg grating is then formed in the waveguide. As the temperature of the waveguide increases, the mechanical tension between the waveguide and the substrate is relieved, such that the peak reflection wavelength of the Bragg grating remains nearly constant.
