Abstract
A tunable grating apparatus includes a plurality of grating structures contained within an optical transmission path. A microelectromechanical (MEMS) actuator is operatively connected to each grating structure for changing the separation between the grating structures and tuning the grating to a desired wavelength selectivity. The grating structures preferably form a Bragg grating.
