| 1. A zero mode waveguide substrate, comprising:
a transparent substrate layer having at least a first surface;
a metal cladding layer disposed upon the first surface of the transparent substrate layer;
an aperture disposed through the cladding layer to the transparent substrate layer, and forming a core region surrounded by
the metal cladding layer, wherein the core is dimensioned to prevent electromagnetic radiation of a frequency greater than
a cut-off frequency from propagating entirely through the core; and
a sacrificial anode disposed upon the cladding layer.
