InP-Based THz Beam Steering Leaky-Wave Antenna
IEEE Transactions on Terahertz Science and Technology, 2021 For mobile THz applications, integrated beam steering THz transmitters are essential. Beam steering approaches using leaky-wave antennas (LWAs) are attractive in that regard since they do not require complex feeding control circuits and beam steering is ...

Blind zone-suppressed hybrid beam steering for solid-state Lidar [PDF]
, 2021 We demonstrate a blind zone-suppressed and flash-emitting solid-state Lidar based on lens-assisted beam-steering technology. As a proof-of-concept demonstration, with the design of a subwavelength-gap 1D long-emitter array and multiwavelength flash beam ...

Demonstration of all-optical beam steering in modulated photonic lattices
, 2005 We demonstrate experimentally all-optical beam steering in modulated photonic lattices induced optically by three beam interference in a biased photorefractive crystal. We identify and characterize the key physical parameters governing the beam steering,

Millimeter-wave diode-grid phase shifters [PDF]
, 1988 Monolithic diode grids have been fabricated on 2-cm square gallium-arsenide wafers with 1600 Schottky-barrier varactor diodes. Shorted diodes are detected with a liquid-crystal technique, and the bad diodes are removed with an ultrasonic probe.
