<title>Fabrication of square spiral photonic crystals by glancing angle deposition</title>

Abstract

Using Glancing Angle Deposition, a novel thin film deposition technique, it is possible to fabricate complex, periodic structures suited for applications in photonic band gap crystals. In comparison to complex lithography processes used to produce conventional structures on the scale of several nanometers, GLAD is ideally suited to a virtual single step deposition, producing a novel tetragonal square spiral crystal structure and having a large predicted band gap of up to 15%.
