Tunable Plasmonic Multispectral Metasurfaces
Abstract
To handle future forms of optical communication at an unprecedently fast speed and low power consumption, we propose to investigate tunable photonic metasurfaces with hybrid resonant coupling with topological carriers in 2D materials. These metasurfaces can serve as a basic junction of novel optical switches. The provoking fundamental inquiry is to better understand the electromagnetic participation with giant magnetoresistive Type II Weyl semimetals of MX2 composition on infrared-wavelength plasmonic emission gratings. This objective will immediately kick off prototyping of plasmonic gratings with various planar configurations created by focused ion beam milling. The materials science of plasmonic gratings will consider both traditional plasma-rich metals and heavy metal oxides with switchable plasma density. This tunability component can enable reversible and ultrafast temperature, voltage, and laser-pulse sensitive emission switching. The advancement of the complementary component is the ÒsandwichedÓ 2D material directly grown on infrared-transparent substrate using an Òupside-downÓ assembly method. This reform effort is supported by the direct atomic layer epitaxial growth of graphene and transition metal dichalcogenides, with the latter particularly focusing on the few-layer Weyl semimetal class. We suggest that the topological Fermi arcs supported by spin-reversed coupled carriers are constrained by the plasmonic grating configuration. The hybridization of groove-based magnetic plasmon polaritons and 2D narrow ribbon hyperbolic exciton plasmon polaritons can support frequency-shifted narrowband color photoemission from infrared light absorption under certain polarization and static magnetic field. Through specialized spectroscopic observation of this quantum-led phenomena on a multi-environment parametric tuning plasmonic cavity device can lead to high-impact literature dissemination of fundamental optoelectronic physics. This funding will help minority serving institution University of North Texas (UNT) develop new capabilities to perform fabrication and experimental investigations of novel optical nano/micro-scale metamaterials. Broad societal ramifications of this study can contribute to todayÕs most pressing technological applications of optical quantum computing, optogenetic biomedical devices, and alternative / renewable energy conversion and management. The community impact of this research directly helps both undergraduate and graduate students of promising backgrounds and academic performance to interface with Air Force Research Laboratory (AFRL) scientists in a research-project speaking engagement. The investigators and departments at UNT will host a prestigious travel award for students engaged in optoelectronic materials research to travel to either an AFRL research site or a AFRL scientist-coattended professional society conference/meeting held in the US. This award can inspire students to explore AFRL research capabilities, undertake AFRL-mentored research positions, and build connections with the US aerospace industry.
