Abstract
Title: New frontiers of nano-photonics: multi-THz imaging and spectroscopfy of grapheneObjective:Specific objectives of our program include:??? to investigate plasmonic reflections and steering by the soliton domain walls ingraphene/hBN moir?? superlatties;??? to fully explore and exploit nano-mechanical tunability of graphene-based moir??heterostructures;??? to investigate both experimentally and theoretically plasmon interactions with the periodically varying conductivity in moir?? superlattices;??? to investigate both experimentally and theoretically plasmon interactions with the periodically varying conductivity in back-gated structures with arrays of gate electrodes;??? to fully explore the fundamental limits to plasmonic losses in graphene;??? to investigate non-linear quantum plasmonic effects in low-loss graphene;??? to advance nano-imaging/spectroscopy to ultra-broad band spectral range and cryogenic temperatures.Approach:Three-pronged approach of our comprehensive research program. A precondition for success of our program is a closely coordinated effort along thefollowing directions:i) Experimental and theoretical exploration of new physics and new (multi)-THz and infrared phenomena in graphene;ii) Design, analysis, modeling, and characterization of graphene-based functional nano-structures; critical assessment of performance of graphene-based THz/IR reconfigurable nano-structures and nano-devices;iii) Development of nano-THz/IR imaging/spectroscopy instrumentation.SOW:The PIs will perform systematic studies of electrodynamics of monolayer graphene and graphene-based heterostructures. They will design, model, fabricate and investigate new types of graphene-based functional structures and devices for photonics and plasmonic applications.Task 1 The team will develop and deploy instrumentation for broad-band nanoimaging and nano-spectroscopy applications operating at cryogenic temperatures.Task 2 The team will demonstrate novel multi-THz emitters installed in thevacuum system of nano-spectroscopy/imaging instruments.Task 3 The team will demonstrate nano-mechanically reconfigurableplasmonic reflectors.Task 4 The team will study Moir?? plasmonic networks for control ofplasmonic propagation.Task 5 The team will build Moir?? photonic crystals for control of nanolight in van der Waals heterostructures.Task 6 The team will build and demonstrate gate arrays and synthetic photonic crystals for nano-light.Task 7 The team will investigate fundamental limits of plasmon dissipation in various forms of graphene (including samples with record high electronic mobility) by means of scanning plasmon interferometry and IR nanoscopy.Task 8 The team will demonstrate plasmonic parametric down-converters.Task 9 The team will explore ballistic plasmonic propagation in high mobility nanostructures.
