Abstract
A photonic crystal structure includes a microcavity (point defect). The photonic crystal structure (or just the microcavity) is doped with materials that exhibit electro-magnetic induced transparency (EIT) so as to increase the non-linear properties of the photonic crystal.
Claims8
A photonic crystal structure containing a microcavity structure that is doped with materials that comprise a single EIT atom or a single EIT quantum-dot, and exhibit electro-magnetic induced transparency (EIT) so as to increase the non-linear properties of said photonic crystal systems.
