Verniered Optical Phased Arrays for Grating Lobe Suppression and Extended FOV
Nathan Dostart, Bohan Zhang, Michael Brand +3
Optical phased arrays (OPAs) which beam-steer in 2D have so far been unable to pack emitting elements at spacing, leading to grating lobes which limit the field-of-view, intr…

Toward Microphononic Circuits on Chip: An Evaluation of Components based on High-Contrast Evanescent Confinement of Acoustic Waves
Yangyang Liu, Nathan Dostart, Miloš A. Popović
We investigate the prospects for micron-scale acoustic wave components and circuits on chip in solid planar structures that do not require suspension. We leverage evanescent guidin…
