First Claim
Patent Images
1. A photonic crystal comprising:
- a plurality of elongated elements formed of a first dielectric material and arranged in a two-dimensional periodic honeycomb lattice; and
a second dielectric material surrounding said plurality of elongated elements and extending between said plurality of first elements, said second dielectric material defining between said elongated elements a plurality of spaces filled with a third dielectric material, said first dielectric material having permittivity that is greater than permittivity of said second dielectric material and permittivity of said third dielectric material.

Abstract
A photonic crystal comprises a plurality of elongated elements formed of a first dielectric material and arranged in a two-dimensional periodic honeycomb lattice. A second dielectric material surrounds the elongated elements and extending between them. The a second dielectric material defines between the elongated elements a plurality of spaces filled with a third dielectric material. The first dielectric material has permittivity that is greater than permittivity of the second dielectric material and permittivity of the third dielectric material.
