Abstract

A Long Range Surface Plasmon Polariton (LRSPP) gold waveguide supported by a thin suspended CYTOP membrane is discussed with respect to biosensing applications. This structure allows for refractive index symmetry through immersion in liquid or gaseous environments. The amorphous fluoropolymer CYTOP is used for the membrane material due to its desirable optical properties. The fabrication steps for the membranes and waveguides are described along with the membranes' mechanical properties determined experimentally through bulge testing. These structures are promising for applications in biological and chemical sensing.
