Abstract
We propose a novel and compact all-optical device for tunable slow and
fast light propagation in parallel coupled structures consisting of two dissimilar
optical nanowires. Advancement/delay tunability is achieved by varying the
spacing between two nanowires. We develop a simplified analytical model to
describe the dependence of achievable time advancement/delay and pulse broadening
on the diameter of optical nanowires and it is indicated that this model agrees
well with numerical results. Simulation results show that achievable maximum
group-index change is about 1.4 and a 10-mm-long device can advance/delay
a 2-ps pulse by 15.9 ps with pulse broadening factor equaling to 2.
