Polymer-based photonic crystals with tunable bandgap

Project description

There has been great interest in investigating the unique optical properties of three-dimensional photonic crystals (PCs), which consist of periodic dielectric structures. In these synthetic crystals, the periodic dielectric structure produces a photonic band gap, similar to the crystal potential of a semiconductor produces an electronic band gap. The unique optical properties of these PCs can be used to design a wide range of optical devices such as filters, waveguides, cavity resonators and chemical and biological sensors. Tunability would expand the spectrum of applications in photonics significantly. The goals of this project are fabrication and optical characterization of polymer-based 3D photonic crystals and tuning of the photonic band gap by changing the lattice constant. This project was completed in 2010.
