Self-referencing photothermal common-path interferometry to measure absorption of Si3N4 membranes for laser-light sails
Tanuj Kumar, Demeng Feng, Shenwei Yin +12
Laser-light sails are a spacecraft concept wherein lightweight "sails" are propelled by high-intensity lasers. We investigated the near-infrared absorption of free-standing membran…
Electrostatic Steering of Thermal Emission with Active Metasurface Control of Delocalized Modes
Joel Siegel, Shinho Kim, Margaret Fortman +6
We theoretically describe and experimentally demonstrate a graphene-integrated metasurface structure that enables electrically-tunable directional control of thermal emission. This…
Thermal runaway of silicon-based laser sails
Gregory R. Holdman, Gabriel R. Jaffe, Min Seok Jang +3
Laser sail-based spacecraft -- where a powerful earth-based laser propels a lightweight outer-space vehicle -- have been recently proposed by the Breakthrough Starshot Initiative a…
Self-stabilizing laser sails based on optical metasurfaces
Joel Siegel, Anthony Wang, Sergey G. Menabde +3
This article investigates the stability of 'laser sail'-style spacecraft constructed from dielectric metasurfaces with areal densities 1g/m. We show that the microscopic opt…
Electronically Tunable Perfect Absorption in Graphene
Seyoon Kim, Min Seok Jang, Victor W. Brar +2
Graphene nanostructures that support surface plasmons have been utilized to create a variety of dynamically tunable light modulators, motivated by theoretical predictions of the po…
