Circularly polarized emission from fluorescent proteins with chiral structures is difficult to discriminate left- or right-handed circularly polarized emission with ease and high sensitivity in a single molecule. A plasmonic chip with a wavelength-size periodic structure deposited with a thin metal film has been used for detecting the enhanced fluorescence in our laboratory. In this study, the polarized transmission properties of the light illuminated to the rear panel of a plasmonic chip substrate were measured. Furthermore, the polarized emission properties of fluorescent molecules, Cy5 and FluoSphere (darkred), immobilized to the chip and the pitch-size dependence of the polarization properties were also measured.
