ABSTRACT:
Apparatuses and methods for adjusting the spectral response of an optical waveguide grating. A controlled extension is imparted to a surface of a support member and an optical waveguide grating is attached to the extended surface. The controlled extension is removed from the support member to create a compressive axial strain on the grating, and the spectral response of the grating is subsequently adjusted by altering the axial strain in the grating.
