Fano resonances and band structure of two-dimensional photonic structures

Improved switching using Fano resonances in photonic crystal structures.

We present a simple and robust structure for realizing asymmetric Fano transmission characteristics in photonic crystal waveguide-cavity structures. The use of Fano resonances for optical switching is analyzed using temporal coupled mode theory in combination with three-dimensional finite difference time domain simulations taking into account the signal bandwidth. The results suggest a signific...

Two-dimensional photonic band-gap structures as quasi-metals.

By considering waves that propagate out of the transverse plane, we show that common high-index materials (e.g., GaAs) with a two-dimensional array of air holes can act in some ways as three-dimensional photonic band-gap structures. In particular, we describe a dielectric quasi-metal that ref lects all propagating light incident from free space.

Fano resonances in nanoscale structures

Modern nanotechnology allows one to scale down various important devices sensors, chips, fibers, etc. and thus opens up new horizons for their applications. The efficiency of most of them is based on fundamental physical phenomena, such as transport of wave excitations and resonances. Short propagation distances make phase-coherent processes of waves important. Often the scattering of waves inv...
