ABSTRACT:
A tunable optical grating device that can be digitally and latchably tuned comprises a length of waveguide including a grating region, and a movable body and fixed substrate attached to the waveguide proximal the grating region. The body is movable from a first position to at least a second position, and in some embodiments to a plurality of positions, along the length of the waveguide to apply a mechanical strain to the grating to shift the wavelength response of the device. The movable body is latchable between the various positions along the length of the waveguide to define a latchably tunable device so that a continuous supply of power is not needed to tune the device. The digitally and latchably tunable optical grating device is useful in WDM communication systems, particularly for adding or dropping channels and for dynamically gain-equalizing optical amplifiers.
