Abstract:
An apparatus having a transducer assembly that includes a waveguide having first and second cladding layers and a core layer between the first and second cladding layers, and a grating structured to couple electromagnetic radiation into the waveguide. The grating has a plurality of elongated slits that are substantially parallel to a longitudinal axis of the waveguide. The apparatus further has a light source mounted adjacent the waveguide to direct light onto the grating.
