Atom tamers Top left: Schematic of how a metasurface shapes a single beam of light into multiple tightly focused beams in a single step. These beams form a series of optical tweezers to trap ...
Abstract: A low-cost, low-profile, electronically controlled millimeter-wave antenna array with two-dimensional wide-angle beam scanning capability is presented. It consists of a planar waveguiding ...
Abstract: This paper presents a CMOS readout circuit for three-dimensional (3D) integration of single-photon avalanche diode (SPAD) arrays. The compact pixel architecture incorporates active quenching ...
