Switchable induced-transmission filters enabled by vanadium dioxide
Chenghao Wan, David Woolf, Colin M. Hessel +6
Abstract: An induced-transmission filter (ITF) uses an ultrathin layer of metal positioned at an electric-field node within a dielectric thin-film bandpass filter to select one tra…
Optical properties of thin-film vanadium dioxide from the visible to the far infrared
Chenghao Wan, Zhen Zhang, David Woolf +13
The insulator-to-metal transition (IMT) in vanadium dioxide (VO2) can enable a variety of optics applications, including switching and modulation, optical limiting, and tuning of o…
Bonding, antibonding and tunable optical forces in asymmetric membranes
Alejandro W. Rodriguez, Alexander P. McCauley, Pui-Chuen Hui +5
We demonstrate that tunable attractive (bonding) and repulsive (anti-bonding) forces can arise in highly asymmetric structures coupled to external radiation, a consequence of the b…
Designing evanescent optical interactions to control the expression of Casimir forces in optomechanical structures
Alejandro W. Rodriguez, David Woolf, Pui-Chuen Hui +5
We propose an optomechanical structure consisting of a photonic-crystal (holey) membrane suspended above a layered silicon-on-insulator substrate in which resonant bonding/antibond…
Achieving a Strongly Temperature-Dependent Casimir Effect
Alejandro W. Rodriguez, David Woolf, Alexander P. McCauley +3
We propose a method of achieving large temperature sensitivity in the Casimir force that involves measuring the stable separation between dielectric objects immersed in fluid. We s…
Non-touching nanoparticle diclusters bound by repulsive and attractive Casimir forces
Alejandro W. Rodriguez, Alexander P. McCauley, David Woolf +3
We present a scheme for obtaining stable Casimir suspension of dielectric nontouching objects immersed in a fluid, validated here in various geometries consisting of ethanol-separa…
