Abstract
Enhanced pump-probe coupling has been experimentally observed in epitaxial Ruby thin film patterned with equidistant gold micro-disks (~ 100 µm), as compared to pure Ruby film. This has been attributed to Fabry-Perot and surface plasmon modes in Ruby/gold film. In case of S polarized pump and probe beam, Fabry-Perot modes leads to a two-wave mixing gain of ~ 1.35. Moreover gain was ~ 1.62 in P polarization case, it has been attributed to coupling of Fabry-Perot and surface plasmon modes. Enhanced coupling for P polarization can lead to improved nonlinear response in thin film geometry. It can find application in thin film based compact photonic devices.
