Dynamically tunable localized surface plasmons using VO2 phase transition Rahimi, Eesa Dynamically tunable localized surface plasmons using VO2 phase transition. Employing phase change materials in plasmonic structure enables it to respond to light dynamically depending the external stimulate. This study investigates the response in presence of vanadium dioxide VO2 phase transition for numbers of novel and classic problems.
To illustrate the significance of optical spectrum tunability by VO2 two important functionalities for the phenomenon have been introduced.
In the first application, a compact and ultrathin plasmonic metasurface is suggested for an ultra-short pulse shaping of transmitted pulse based on linear filtering principle of electromagnetic wave.
It is demonstrated that the tunable optical filter by VO2 phase transition can compensate realtime input carrier frequency shifts and pulse span variations to stabilize the output pulse.
Second application is dedicated to the field of intrachip optical communication which shows how VO2 phase transition can effectively switch a communicating antenna on and off.
A substantial directional gain switching is obtained by employing VO2 phase transition to alternate resonances of a Yagi-Uda antenna elements. VO2 scattering functionality in absence of localized surface plasmons is studied to illustrate their promising performance in light reflection.
Finally the behavior of localized surface plasmon resonators is studied and chimera stats which are the concurrent combination of synchronous and incoherent oscillations in a set of identical oscillators is shown for the first time in the optical regime.Thesis for the degree of Master of Science in Engineering Physics Towards Plasmon-Enhanced Heterogeneous Catalysis on Metal Nanoparticles Jenny Andersson.
My overall research focuses on the application of optics/photonics to problems in biology and medicine.
My current research includes plasmonic antennas for enhancing light matter interactions, real-time DNA and protein microarrays, and neural photonics - using light to effect and/or record neural signals.
