An over 300-fold reduction of the group velocity on a silicon chip via an ultra-compact photonic integrated circuit using low-loss silicon photonic crystal waveguides that can support an optical mode with a submicrometre cross-section is experimentally demonstrated.Abstract:
It is known that light can be slowed down in dispersive materials near resonances. Dramatic reduction of the light group velocity-and even bringing light pulses to a complete halt-has been demonstrated recently in various atomic and solid state systems, where the material absorption is cancelled via quantum optical coherent effects. Exploitation of slow light phenomena has potential for applications ranging from all-optical storage to all-optical switching. Existing schemes, however, are restricted to the narrow frequency range of the material resonance, which limits the operation frequency, maximum data rate and storage capacity. Moreover, the implementation of external lasers, low pressures and/or low temperatures prevents miniaturization and hinders practical applications. Here we experimentally demonstrate an over 300-fold reduction of the group velocity on a silicon chip via an ultra-compact photonic integrated circuit using low-loss silicon photonic crystal waveguides that can support an optical mode with a submicrometre cross-section. In addition, we show fast (approximately 100 ns) and efficient (2 mW electric power) active control of the group velocity by localized heating of the photonic crystal waveguide with an integrated micro-heater.read more

TL;DR: Owing to the very small footprint of the delay line, a fully integrated device is feasible, also featuring more complex and elaborate filter functions, and both notch and band-pass microwave filters that can be tuned over the 0-50-GHz spectral band are demonstrated.

TL;DR: In this article, a single photon generation from individual self-assembled InGaAs quantum dotscoupled to the guided optical mode of a GaAs photonic crystal waveguide was investigated, and the results obtained demonstrate that such nanostructures can be used to realize an on-chip, highly directed single photon source with single mode spontaneous emision couplinge¯¯encies in excess of 85 % and the potential to reach maximum emission rates > 1 GHz.
