We demonstrate the first low-loss, low-return-loss FC/PC connector for a single-mode, hollow-core fiber. Connector loss of 0.3dB and return loss of −31.3dB was measured, and a 200m HCF jumper with connectors on both ends was fabricated.
We demonstrate the first measured dual-hollow-core photonic bandgap silica fiber. We examine its bend-induced coupling characteristics both theoretically and experimentally. Varying the bend diameter of the fiber allows control of the resonant coupling wavelength.
