Photonic crystal based circuitry fabricated using laser-assisted processes

Recently, photonic crystals (PCs) have gained interest due to their ability to influence the propagation of light [1]. This paper describes a simple and novel approach for the fabrication of micron and nanometer scale photonic crystal based circuitry with an arbitrary degree of control. Laser ablation using a femtosecond Ti:Sapphire [2] laser is used to form a template from which the photonic crystal device is cast
