(Color online) (a) Cross-section schematic of the n-UV PC biosensor and measurement setup and (b) scanning electron microscopy image of the one-dimensional periodic surface structure as replicated into low RI porous spin-on glass.
(Color) RCWA simulations of resonant electric field profile for the (a) n-UV biosensor and (b) n-IR biosensor . The field is seen to be more tightly confined to the surface of the n-UV biosensor. The plane-wave light source excites the structure from below along the axis and has unit amplitude. The and axes indicate the extent of the simulation region, in microns.
(Color online) Experimental results of the (a) bulk and (b) surface sensitivity experiments. The bulk shift coefficient is calculated by the slope of the line that is obtained by plotting the PWV shift as the RI of the material at the surface of the biosensor is changed from air to that of water and IPA , and the maximum surface shift for a layer of PPL deposited at the biosensor surface is .
