ABSTRACT: We demonstrate for the first time, to best of our
knowledge, that by engineering the states of a system of cavities it is
possible to control photon transitions using non-adiabatic refractive index
tuning. This is used to realize a novel photon transitions that are independent
of the refractive index sign. In particular, we show through coupled mode
theory and FDTD simulations that red shifts are possible in silicon resonators
using the free-carrier plasma dispersion refractive index reduction.
