A tunable optical fiber grating device for tuning optical characteristic responses of an optical grating area of an optical fiber includes an elongated beam member defining a neutral plane with a first and a second ends and adapted to receive the fiber' therealong. A securing member continuously secures the grating area all along the beam member between its ends and generally parallel to the neutral plane to allow for transmission of a bend of the beam member about the neutral plane to the grating area. A fixed support member has a screw for releasably securing the first end of the beam member within the neutral plane, and a mobile support member has a slotted element to slidably receive the second end of the beam member within the neutral plane. The mobile support member displaces the second end relative to the first end substantially perpendicularly to the neutral plane to bending the beam, thereby stretching or compressing the grating area for tuning the optical characteristic responses of the optical fiber depending on the direction of the bend.
