Photonic device structures such as photonic crystals, photonic wires and optical metamaterials all with submicron features can be described as nanophotonic. Many of these devices and structures can be used as sensors. The usual approach is to photonic sensing is to change the refractive index of a surrounding medium. Here we consider several nanophotonic sensing systems, including asymmetric split ring resonators, photonic wire cavities and polymer Bragg gratings. We compare the relative merits of high Q structures with a small shift in wavelength from the analyte versus low Q structures with a large shift in wavelength. © 2012 IEEE.

Abstract
Photonic device structures such as photonic crystals, photonic wires and optical metamaterials all with submicron features can be described as nanophotonic. Many of these devices and structures can be used as sensors. The usual approach is to photonic sensing is to change the refractive index of a surrounding medium. Here we consider several nanophotonic sensing systems, including asymmetric split ring resonators, photonic wire cavities and polymer Bragg gratings. We compare the relative merits of high Q structures with a small shift in wavelength from the analyte versus low Q structures with a large shift in wavelength. © 2012 IEEE.File in questo prodotto:
