摘要
We report, for the first time, bandgap guidance above 3 m in a silica based air-core photonic crystal fiber. The peak of the bandgap is at 3.14 m with a typical attenuation of similar to 2.6 dB m(-1). By further optimization of the structure, modeling suggests that a loss below 1 dB m(-1) should be achievable, greatly extending the useful operating range of silica-based single-mode fibers. Such fibers have many potential applications in the mid-IR, offering an alternative to fluoride, tellurite or chalcogenide glass based optical fibers for chemical and biological sensing applications.
