Abstract
A compression-tuned Bragg grating-based laser includes a pair of optical grating elements wherein at least one of the grating elements is tunable by a compression device The grating elements may include either an optical fiber having at least one Bragg grating impressed therein encased within and fused to at least a portion of a glass capillary tube or a large diameter waveguide grating element having a core and a wide cladding. The tunable grating element(s) are axially compressed, which causes a shift in the reflection wavelength of the gratings without buckling the element. The shape of the element may be other geometries (e.g., a “dogbone” shape) and/or more than one grating or pair of gratings may be used and more than one fiber or core may be used. A gain element, such as Erbium doped fiber, is optical disposed between the grating elements to provide the lasing cavity.
