Abstract

A new method for enhancing the wavelength selectivity and responsivity of hybrid dye/ superconductor optical sensors is described. Here, reflective "mirror layers" deposited atop the high-temperature superconductor, YBa2Cu3O7-δ, 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 studies suggest that the inclusion of the mirror layer serves to enhance the wavelength selectivity by reducing the amount of off-resonance signal generated by the detector. On the other hand, the on-resonance signals captured by the dye layer are effectively sensed by the superconductor element. Measurement of the wavelength-dependent optical responsivity of the mirror-layer-modified hybrid detectors shows that energy transfer between the dye and superconducting elements is not diminished by the presence of this reflective layer.
