Claim 0:
1. A sensor comprising:
an optical slab waveguide having one or more target regions, said target regions configured to trap one or more targets of interest;
said optical slab waveguide adapted to receive one or more input optical beams from one or more light sources, wherein the one or more input optical beams generate a plurality of propagating optical waves in said optical slab waveguide;
said propagating optical waves interact with and are modified by said
one or more target regions to create an optical output wavefront at an output port of the slab waveguide; and
said optical output port is configured to allow the optical output wavefront to form a two-dimensional diffraction pattern upon exiting said output port, wherein a power distribution over said two-dimensional diffraction pattern is indicative of the interaction between said propagating optical waves and said one or more target regions.
