(a) Schematic of PC designed in this work. The dimensions are as follows: period , grating depth , thickness , and thickness . The grating width is 50% of the period. (b) Atomic force micrograph of PC fabricated by nanoreplica molding, showing the measured period of and a grating depth of , in good agreement with the simulated structure.
(a) Simulated and (b) measured transmission efficiencies as a function of wavelength for white light illumination of the PC at normal incidence with either TM-polarized incident light or TE-polarized incident light.
Intensity profile as a function of distance for a line of fluorescent image pixels profiling three spots of cyanine-5 conjugated streptavidin for both the glass slide and the PC under normal incidence illumination. Fluorescence intensity is plotted on a logarithmic scale.
Spot intensities and signal-to-noise ratios for photonic crystal and glass slide at identical scan conditions over 96 replicates per slide. Coefficients of variation (CV) are included for each scan condition.
