512-Element Actively Steered Silicon Phased Array for Low-Power LIDAR

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate the highest yet-reported element count actively-steered optical phased array with record low array power consumption of <1.8W. We show 2D steering over a 70 x 14 degree field of view while pumped by an integrated InP/silicon laser.
