ABSTRACT
We show that a high-Q optical resonance can be created dynamically, by inducing a photonic transition between a localized state and a one-dimensional continuum through refractive index modulation. In this mechanism, both the frequency and the external linewidth of a single resonance are specified by the dynamics, allowing complete control of the resonance properties. An example using photonic crystal heterostructure cavity is demonstrated with numerical simulation. We also show that the reported effect can be accomplished with realistic index modulation strength and frequencies.
