Paper Abstract

A unique corrugated-thin-metal-film structure suitable for integration with semiconductor photodetectors, is investigated. For fluorescent spectral monitoring, this structure provides a number of important detection features including fluorescence enhancement for molecules located near the surface of the sensor, excitation wavelength shielding and narrow bandpass filtering of detected wavelengths. Surface dielectrics with chemical or biological-specific properties may also be incorporated into the sensor for additional selectivity.
