Abstract

A strategy for increasing the wavelength selectivity and responsivity of hybrid dye/superconductor optical sensors is described. Here, reflective 'mirror layers' deposited on the top surface of YBa2Cu3O7-δ thin film devices are used to enhance the optical performance characteristics of such hybrid sensors. Quantification of the wavelength-selectivity for such detector structures is detailed for both dye/high-Tc superconductor and dye/mirror-layer/high-Tc superconductor systems. Optical response studies of the structures suggest that the inclusion of the mirror layer serves to enhance the wavelength-selectivity of the detector. Consequently, only the on-resonance signals captured by the dye layer are effectively sensed by the superconductor element. Measurements of the spectral response properties of the mirror layer-modified hybrid detectors show that energy transfer between the dye and superconducting elements is not diminished by the presence of this reflective layer.
