Tunable optical fiber gratings device
First Claim
1. A tunable optical fiber gratings device for tuning optical characteristic responses of a longitudinal optical grating area of an optical fiber, said device comprising an elongated beam member defining a neutral plane with a first and a second ends and adapted to receive said fiber therealong, a securing member for continuously securing said optical grating area all along said beam member between said first and second ends and generally parallel to said neutral plane to allow for transmission of a bend of said beam member about said neutral plane to said optical grating area, a fixed support member having a clamping means for releasably securing said first end of said beam member within said neutral plane, and a mobile support member having a directing means for slidably receiving said second end of said beam member within said neutral plane, said mobile support member displacing said second end relative to said first end substantially perpendicularly to said neutral plane and bending the same, thereby stretching or compressing said grating area of said fiber for tuning said optical characteristic responses of said optical fiber depending on a direction of said bend.

Abstract
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.
