    摘要: A broadband spectral power generator in a multimode optical fiber utilizes a standard multimode fiber that is coiled. A plate is placed on the coiled fiber and a force is applied to compresses the coiled fiber and thereby increase the interactions between the compressed windings and induce modal mixing and birefringence in the fiber. In addition, the compression causes additional non-linear processes to be excited and occur in the compressed fiber coil to generate more broadband light. This allows for better "mixing" of the spatial beam in the multimode fiber coil and allows for the various modes to overlap. The multimode fiber coil is made of silica, silicate, germinate, phosphate, fluoride, chalcogenide, or telluride. The compressed coiled fiber may be driven by a laser providing more than one wavelength output and this greatly increases the amount of nonlinear mixing in the fiber for a greatly enhanced spectral coverage.

    摘要: A method of thermally poling a silica based waveguide (12) comprises exposing a region of the waveguide (12) to an electric field (for example, via capillary electrodes (22, 24) inserted into holes in the waveguide); directing a laser beam (18) into the region exposed to the electric field to effect localised heating of the region via direct absorption; and scanning the laser beam (18) over the region at a rate selected to avoid heating of the region above the glass transition temperature. Reversing the electric field while scanning the laser beam (18) allows the formation of periodic poled gratings. The waveguide (12) can comprise an optical fibre.
