Power circulation via negative energy-flux wormholes in optical nanowaveguides
Abbreviated Journal Title
WAVE-GUIDE; SUPERCONTINUUM; NANOWIRES; WIRES; Optics
We show that energy circulation within a pulse is possible when it propagates in a high-contrast dielectric nanowire. This process is accomplished through electromagnetic "wormhole" regions, in which the Poynting vector associated with the guided mode is negative with respect to the direction of propagation. For demonstration purposes this mechanism is elucidated in AlGaAs and silicon nanowaveguides. The effect of dispersion on the power circulation is also considered.
