Abstract

We show that Silicon Nitride (Si₃N₄) photonic crystal (PhC) resonators are powerful building blocks to realize biocompatible photonic devices based on spontaneous emission engineering of nanoemitters in the visible spectral range. The versatility of this technological platform is demonstrated also in biological applications, where nanocavity modes are coupled to DNA strains marked with Cyanine 3 (Cy3) organic dyes and antibodies bounded to fluorescent proteins (TRITC).
