High Transmission through Sharp Bends in Photonic Crystal Waveguides.
TLDR
A simple one-dimensional scattering theory model with a dynamic frequency-dependent well depth to describe the transmission properties is proposed and highly efficient transmission of light around sharp corners in photonic band-gap waveguides is demonstrated.Abstract:
We demonstrate highly efficient transmission of light around sharp corners in photonic band-gap waveguides. Numerical simulations reveal complete transmission at certain frequencies, and very high transmission $(g95%)$ over wide frequency ranges. High transmission is observed even for 90\ifmmode^\circ\else\textdegree\fi{} bends with zero radius of curvature, with a maximum transmission of 98% as opposed to 30% for analogous conventional dielectric waveguides. We propose a simple one-dimensional scattering theory model with a dynamic frequency-dependent well depth to describe the transmission properties.read more

Photonic crystals: putting a new twist on light
TL;DR: In this article, the authors describe the photonic bandgap as a periodicity in dielectric constant, which can create a range of 'forbidden' frequencies called a photonic Bandgap.

Fano resonances in nanoscale structures
TL;DR: In this paper, the authors introduce the concept of Fano resonances, which can be reduced to the interaction of a discrete (localized) state with a continuum of propagation modes, and explain their geometrical and/or dynamical origin.

TL;DR: The bound state energies as well as the transmission and reflection matrices and the nature of the resonances that occur in the vicinity of channel thresholds are determined and the numerical results confirm analytic predictions.
