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.

Claims (8)

1. 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.

2. The microcavity structure of claim 1 , wherein said materials are doped using a scanning tunnel microscope related techniques.

3. The microcavity structure of claim 1 , wherein said materials are doped with a plurality of EIT atoms.

4. The microcavity structure of claim 3 , wherein said materials are doped using a scanning tunnel microscope.

5. The microcavity structure of claim 1 , wherein said photonic crystal structure is a three dimensional photonic crystal structure.

6. The microcavity structure of claim 1 , wherein said photonic crystal structure is a two dimensional photonic crystal structure.

7. The microcavity structure of claim 1 , wherein said photonic crystal structure is a multi-layered structure of varying indices.

8. The microcavity structure of claim 7 , wherein said multi-layered structure forms a multi-layered film.
