报道了一种利用压力辅助熔融玻璃填充法制备的硫族化物-二氧化硅混合光子晶体光纤。光子带隙的指导是在一个连续的厘米长的硫族化物链的直径为1.45 μ m的六边形阵列的中心放置在二氧化硅芯。在包层的通带中，当通过二氧化硅芯的透射非常弱时，硫属化物束以对应于Mie共振的不同模式图案发光。在这些通带之间的光谱区域中，观察到强带隙引导，其中二氧化硅芯传输损耗低60 dB/cm。压力辅助制造方法开辟了将复杂的玻璃基器件集成到光纤电路中的新方法，其在超连续谱产生、磁光、波长选择器件和具有高单位长度增益的稀土掺杂放大器中具有潜在的应用。(C)2011年美国光学学会
We report a hybrid chalcogenide-silica photonic crystal fiber made by pressure-assisted melt-filling of molten glass. Photonic bandgap guidance is obtained at a silica core placed centrally in a hexagonal array of continuous centimeters-long chalcogenide strands with diameters of 1.45 mu m. In the passbands of the cladding, when the transmission through the silica core is very weak, the chalcogenide strands light up with distinct modal patterns corresponding to Mie resonances. In the spectral regions between these passbands, strong bandgap guidance is observed, where the silica core transmission loss is 60 dB/cm lower. The pressure-assisted fabrication approach opens up new ways of integrating sophisticated glass-based devices into optical fiber circuitry with potential applications in supercontinuum generation, magneto-optics, wavelength selective devices, and rare-earth-doped amplifiers with high gain per unit length.
