Event Title

2D Confinement of Guided-Wave Plasmon Polariton Modes

Research Mentor(s)

Leger, Janelle

Description

Surface plasmon polaritons (SPPs) have long been a topic of interest in the field of optics. SPPs are interfaced-confined excitations that propagate along metal-dielectric interfaces and can be accessed in tri-layer metal-insulator-metal (MIM) waveguide structures. Our research group has altered the materials used to build MIM waveguides by increasing the index of the central layer to access what we call guided-wave plasmon polariton modes, which have increased propagation lengths compared to those of traditional SPPs in certain regions of phase space. To further our research into increased propagation lengths of these modes, we have altered the waveguide structure again, but this time by adjusting the dimensions of the waveguide rather than the materials. This is what we call two dimensional (2D) confinement of bulk waveguides. We present preliminary characterization of 2D-confined MIM waveguides, as 2D confinement is hypothesized to increase mode propagation more than what was already discovered.
