Diffraction enhancement via Bloch Surface Waves in a-SiN:H multilayers

Using the excitation of a Bloch Surface Wave (BSW), we demonstrate a 45-fold diffraction enhancement for a protein grating printed on a-SiN:H multilayers. This may lead to a new generation of high sensitivity diffraction-based biosensors.
