Diamond 2D-photonic crystals for highly sensitive label-free biosensors
Overview & Synopsis
We demonstrate design and fabrication of 2D diamond photonic crystals (PhC) allowing record bio-sensing sensitivities higher than surface plasmon resonance (SPR) state of the art. Polycrystalline diamond is probed directly from the surface with angular reflectivity measurements. A 2D PhC was designed with a mode frequency hardly varying with the interrogation angle. Optical experiments were performed at different angles and wavelengths to validate the simulations of the band diagram. The measured reflectivity spectrum is in good agreement with the simulated one.
