A novel approach that enables long range hybrid plasmonic modes to be supported in asymmetric structures will be discussed. Examining the modal behavior of an asymmetric hybrid plasmonic waveguide (AHPW) reveals that field symmetry on either side of the metal is the only necessary condition for plasmonic structures to support long range propagation. In this talk we shall demonstrate that this field symmetry condition can be satisfied irrespective of asymmetry in waveguide structure, material, or even field profile. The versatility in the choice of parameters allows for long range hybrid plasmonic modes to be achieved in generic structures. Altering the existing limitations of these performance metrics (mode area and propagation losses) can have significant implications on the designs of active devices. As illustrative example, the utility of these waveguide designs is demonstrated when combined with novel material such as ITO to realize optoelectronic components such as filters, modulators and switches with record footprint, performance and insertion losses.
