3D schematic drawing of the presented serpentine OPA design. Grating antennas, phase shifters, and the additional lengths between two serpentine sections are circled in green, white, and black, ...

STRL is promoting research on optical phased arrays *1 that can control the direction of a light ray at high speed by applying voltage, toward the realization of AR glasses capable of viewing natural ...

Though radar is the more prevalent object detection system, the lesser-known ladar -- radar that uses lasers instead of radio frequencies -- produces a more detailed result. The problem though, is ...

WASHINGTON — Researchers have developed a new chip-based beam steering technology that provides a promising route to small, cost-effective and high-performance lidar (or light detection and ranging) ...
