Abstract

See full text

Techniques for enhanced fluorescence include a Tamm substrate for a target optical frequency comprising a metal nanoscale layer deposited on a Bragg grating. The Bragg grating includes multiple dielectric layers including multiple high index of refraction layers alternating with multiple low index of refraction layers. The dielectric layers are parallel to the metal nanoscale layer; and, the thickness of each dielectric layer is about a fourth of a wavelength of the target optical frequency in the layer. The metal nanoscale layer is configured to host a fluorophore such that an S polarized emission from the fluorophore at the target optical frequency propagates out of the substrate perpendicular to the plurality of dielectric layers.
