Presence of photonic bands and band-gaps in periodic networks

Dispersion controlled by network layout

Abstract

A resonant guided wave network (RGWN) is an approach to optical materials design in which power propagation in guided wave circuits enables material dispersion. The RGWN design, which consists of power-splitting elements arranged at the nodes of a waveguide network, results in wave dispersion which depends on network layout due to localized resonances at several length scales in the network. These structures exhibit both localized resonances with Q ~ 80 at 1550 nm wavelength as well as photonic bands and band-gaps in large periodic networks at infrared wavelengths.
