Directly-Written Metallic Photonic Crystals for Sensor Applications

Article Preview

Abstract:

Metallic photonic crystals (MPC) consisting of gold nanowires on a waveguide layer of indium tin oxide (ITO) has been fabricated using interference ablation. A sensor device based on this kind of waveguide MPCs is demonstrated by the measurements on the concentration change in the glucose/water solution. A special definition is formulated for the amplitude sensor signal for such a sensor device, which shows excellent linear dependence on the change in the environmental refractive index.
