dc.description.abstractThis thesis addresses some of the issues in the field of plasmonics such as the high optical loss associated with waveguiding and difficulty in integrating plasmonic coupling in a III-V LED. Through our research, we show ways of mitigating loss using metal assisted photonic mode guiding. This mode offers both long propagation and high confinement factor near its cut-off limit. We also introduce a surface smoothing technology using gas cluster ion beam irradiation to obtain high quality ultrathin, smooth silver structures for further reducing the optical loss of plasmonic devices. In addition, we demonstrate a way of introducing SPP coupling into an LED without having to modify the LED layer structure. This is a textured type of plasmonic LED structure that can provide a strong coupling even at relatively large distances. This design offers a simple approach to fabricate high speed LEDs for applications in visible light communications.
