Abstract
An apparatus and method for adjusting the spectral response of a selected channel within an optical waveguide grating includes a grating attached to a support member. An adjusting mechanism applies two bending moments to the grating support member on both sides of the selected channel. The spectral response of the selected channel is adjusted by altering the bending moments.
