1. A method of fabricating a photonic crystal, comprising:
- providing a substrate;
forming within said substrate a plurality of elongated elements of a first dielectric material in a two-dimensional periodic honeycomb lattice;
forming a layer of a second dielectric material over said substrate to a thickness such that said second dielectric material continuously extend between said plurality of elongated elements, said second dielectric material having permittivity less than permittivity of said first 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 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.
