Implementations of quantum information require single-photon detectors (SPDs) with high detection efficiency (DE) at a wavelength of 940 nm, which is a challenge for the available semiconducting SPDs. Superconducting nanowire SPDs (SNSPDs) are capable of detecting visible and near-infrared single photons with high DE. However, these detection capabilities place stringent design requirements on the...
Error-free transmission at 40, 36, and 30 Gbit/s across 50, 200, and 400 m, respectively of multimode fiber is achieved with energy dissipation of 119, 128 and 127 fJ/bit using 850 nm vertical-cavity surface-emitting lasers.
We have demonstrated bulk (51 mum thick) photonic metamaterial based on anodized alumina membranes filled with silver. The material is highly anisotropic and follows the hyperbolic dispersion law at lambda>0.84 mum.
Self-imaging and spectral filtering due to multimode interference are utilized to demonstrate an all-fiber laser with active multimode fiber that generates linearly polarized diffraction limited light.
Based on a novel nonlinear optical loop mirror, a RF photonic phase modulator with broad operation bandwidth is experimentally demonstrated. A full O~?? phase-shift tuning range can be achieved using a single external control light.
We demonstrate tunable dispersion slope compensation for 40-Gb/s WDM systems using two inverse 3rd-order chirped gratings. The inherent errors in a single grating are eliminated. The slope range is -20 to +20 ps/nm2over a 5-nm bandwidth.
