Resonances in photonic crystals and nanophotonics
The developments of photonic crystals and nanophotonic
devices allow unprecendented control over the behavior of light. One
of the very exciting aspects of these structures are the creation of
wavelength-scale and sub-wavelength-scale resonances. We will argue
that these resonances form a new basis for exploring optical physics.
As examples, we will report on some of recent works on using Fano
interference to construct mechanically tunable photonic crystal
structures that are highly compact; on coherent stopping, storage and
time-reversal of light; and on new artificial optical materials with
geometrically controlled refractive index.
