Cascaded frequency conversion of highly charged femtosecond spatiotemporal optical vortices
Qingqing Liang, Qiyuan Zhang, Dan Wang +6
The degrees of freedom inherent in spatiotemporal optical vortices (STOV's) afford intriguing opportunties to manipulate complex light fields for broad applications such as optical…
Broadband Diffractive Solar Sail
Prateek R. Srivastava, Ryan M. Crum, Grover A. Swartzlander
The transverse radiation pressure force and acceleration is compared for two parametrically optimized designs: prismatic and two-pillar metasurface gratings. The numerical results…
High Forward Thrust Metasurface Beam-Riding Sail
Prateek R. Srivastava, Apratim Majumdar, Rajesh Menon +1
The radiation pressure force and torque on a one-dimensional bi-grating composed of a Si-SiO_2 high contrast binary metagrating is analyzed for the purpose of stable beam riding wh…
Theory of Radiation Pressure on a Diffractive Solar Sail
Grover A. Swartzlander
Solar sails propelled by radiation pressure enable space missions that cannot be achieved using chemical rockets alone. Significant in-space propulsion for missions such as a solar…
Measurements of Radiation Pressure owing to the Grating Momentum
Ying-Ju Lucy Chu, Eric M. Jansson, Grover A. Swartzlander
The force from radiation pressure owing to the grating momentum was measured for a thin transmissive fused silica grating near the Littrow angles at wavelengths of 808 nm and 447 n…
Radiation Pressure on a Diffractive Sailcraft
Grover A. Swartzlander
Advanced diffractive films may afford advantages over passive reflective surfaces for a variety space missions that use solar or laser in-space propulsion. Three cases are compared…
Zernike amplitude pupil apodization for vortex coronagraphy with obscured apertures
Garreth J. Ruane, Mark R. Dennis, Grover A. Swartzlander
A set of pupil apodization functions for use with a vortex coronagraph on telescopes with obscured apertures is presented. We show analytically that pupil amplitudes given by real-…
Vortex-phase filtering technique for extracting spatial information from unresolved sources
Garreth J. Ruane, Prachyathit Kanburapa, Jiaxuan Han +1
A white light vortex coronagraph was used to experimentally achieve sub-resolution detection. The angular location of the centroid, , and the angular extent of circular pinhole…
Nodal Areas and Structured Darkness
Garreth J. Ruane, Sergei Slussarenko, Lorenzo Marrucci +1
Generalized beams of light that are made to turn inside out, creating black nodal areas of total destructive interference are described. As an example we experimentally created an…
