摘要：
A waveguide grating device controlling Bragg wavelength after manufacture of the device includes an optical waveguide on a substrate. A variable stress is applied to a waveguide grating in part of the waveguide to bend at least the portion of the substrate including the waveguide grating, changing the Bragg wavelength.
