Surface plasmon resonance (SPR) sensors have grown in popularity owing to their sensitivity, precision, and capacity for a variety of applications, including detection, monitoring, sensing, among others. Sensitivity resolution are two areas where this technology has room development. A plasmonic biosensor based on an asymmetric slotted PCF structure with extremely high sensitivity been describe...

In this work, we have experimentally and theoretically studied negative refraction of electromagnetic waves by a metallodielectric photonic crystal. We showed that by adding a periodic dielectric perturbation to the unit cell of a metallic photonic crystal, it is possible to increase the range of incidence angles at which the electromagnetic waves are negatively refracted. We obtained negative ...

We describe a novel scheme based on evanescent guided-wave coupling for optically interfacing between conventional fiber-optic and planar photonic crystal devices such as waveguides and resonant cavities. By considering the band structure of bulk photonic crystal slabs, we analyze the k space properties of a linear defect waveguide and establish a set of design rules to ensure efficient evanesc...
