Abstract

Thermodynamic optimization of waveguide sensors is considered. A waveguide geometry is shown to improve the detection ability of a sensor device by a factor of (NA)2/N relative to a thin-film analyzer with a transverse excitation, NA being the numerical aperture of the waveguide and N being the density of species to be detected. For ultralow densities of species, the sensitivity of a waveguide sensor is shown to be orders of magnitude higher than the sensitivity of a thin-film analyzer.
