ABSTRACT:
A large diameter optical waveguide, grating, and laser includes a waveguide10having at least one core12surrounded by a cladding14,the core propagating light in substantially a few transverse spatial modes; and having an outer waveguide dimension d2of said waveguide being greater than about 0.3 mm. At least one Bragg grating16may be impressed in the waveguide10.The waveguide10may be axially compressed which causes the length L of the waveguide10to decrease without buckling. The waveguide10may be used for any application where a waveguide needs to be compression tuned, e.g., compression-tuned fiber gratings and lasers or other applications. Also, the waveguide10exhibits lower mode coupling from the core12to the cladding14and allows for higher optical power to be used when writing gratings16without damaging the waveguide10.The shape of the waveguide10may have other geometries (e.g., a “dogbone” shape) and/or more than one grating or pair of gratings may be used and more than one core may be used. The core and/or cladding12,14may be doped with a rare-earth dopant and/or may be photosensitive. At least a portion of the core12may be doped between a pair of gratings50,52to form a fiber laser or the grating16or may be constructed as a tunable DFB fiber laser or an interactive fiber laser within the waveguide10.The waveguide may resemble a short “block” or a longer “cane” type, depending on the application and dimensions used.
