A new type of optical sensor is proposed, based on the resonant excitation of Tamm surface plasmons. These electromagnetic modes, confined at the interface between a noble metal layer and a onedimensional photonic crystal (Distributed Bragg Reflector, DBR), offer a promising platform combining high sensitivity and facile instrumentation. Non-intrusive optical interrogation is carried out by simple normalincidence reflectivity measurement for a fixed wavelength of illumination, or by acquisition of a full reflectance spectrum with white light illumination.
