Slow Light in Optical Waveguides
As evidenced by this Volume, there has been a flurry of activity over the last decade on tailoring the dispersive properties of optical materials [1]. What has captured the attention of the research community were some of the early results on creating spectral regions of large normal dispersion [2–4]. Large normal dispersion results in extremely small group velocities, where the group velocity ...
متن کاملLoss engineered slow light waveguides.
Slow light devices such as photonic crystal waveguides (PhCW) and coupled resonator optical waveguides (CROW) have much promise for optical signal processing applications and a number of successful demonstrations underpinning this promise have already been made. Most of these applications are limited by propagation losses, especially for higher group indices. These losses are caused by technolo...

متن کاملSlow-light vortices in periodic waveguides
We reveal that the reduction of the group velocity of light in periodic waveguides is generically associated with the presence of circulating energy flows or optical vortices. We show that the energy flows are gradually frozen for slow-light at the Brillouin zone edge, whereas vortices persist for slow-light states having non-vanishing phase velocity inside the Brillouin zone. We also demonstra...
متن کاملLocalization in silicon nanophotonic slow-light waveguides
Slowing down light on a chip can lead to the development of optical buffers1, filters2,3 and memory elements4 useful for optical interconnects and for resonantly enhanced chip-based nonlinear optics. Several approaches to slow light rely on the phenomenon of light interference in a sequence of coupled resonators; however, light interference is also responsible, in disordered structures, for the...
