A Kagome hollow-core PCF with a record loss of 40dB/km is used to deliver 74μJ and 850fs laser pulse with little propagation pulse-distortion, and to compress a 105μJ laser pulse from 900fs to 300fs.
We report on hollow-core Kagome fiber with a record loss of 70dB/km and operating at ∼800nm. We show experimentally that the bending-loss is limited by coupling between the guiding core mode and the modes in the cladding holes.
A Kagome-lattice hollow-core photonic crystal fiber with a hypocycloid-shaped core enhances the coupling-inhibition between the core- and cladding-modes, thus providing an optical attenuation <;250dB/km. This rivals the state-of-the-art photonic bandgap hollow-core fibers is demonstrated.
We propose and demonstrate a high speed carrier-reuse wavelength division multiplexed passive optical network (WDM-PON) based on injection locked Fabry-Perot laser diodes (FP-LD). Experiments for both downlink and uplink transmission at 10 Gb/s show very good BER performance with a large operating range.
