Photonic crystal device

A method of manufacturing an optical device having a first layer functioning as an optical waveguide layer and a second layer functioning as a base layer, the method comprising the steps of:

• providing a resist layer on a surface of a first medium;
• removing portions of the resist layer to form vacancies;
• removing portions of the first medium corresponding to the vacancies to create cavities in the first medium, the depth of the cavities being less than a thickness of the first medium;
• removing the resist layer completely;
• filling the cavities in the first medium with a second medium;
• and
• removing any excess film of the second medium from the surface of the first medium.

An optical device comprising:

• a first medium having a thickness, the first medium at least partially forming a first layer and a second layer of the optical device, the first layer having a plurality of periodically spaced protruding portions surrounded by concave portions having a depth less than the thickness of the first medium;
• and
• a second medium being dispersed within the concave portions surrounding the plurality of periodically spaced protruding portions of the first layer,
• wherein the first layer is a photonic crystal, and the second layer is formed entirely of the first medium.
