Abstract

In this letter, we report the design and development of improved step-index silver halide (AgClBr) single mode fibers. These fibers exhibited round and symmetrical field mode distribution while efficiently suppressing the higher order modes. The losses of the fundamental mode were 10-20 dBm at λ=10.6 μm, and the minimum fiber length needed for single mode operation was ∼50 cm. These fibers will be useful as spatial filters for middle infrared interferometry.
