| Abstract | A novel optical antenna for integrated LIDAR with optical phased arrays is proposed and simulated. A HCG structure is used to achieve extremely efficient emission. The emission efficiency is as high as 93.94% at 1550 nm, which exceeds 50% in a range of wavelength from 1480 nm to 1620 nm. The antenna can achieve a perfect grating lobe suppression with background suppression of 28.4dB when the phase difference between adjacent waveguides is 0. A 16-wire optical phased arrays LIDAR can easily achieve a scan range of ±22.820.2 with a beam width of 2.4x2.5, by employing the optical antenna proposed. © 2018 ECS Transactions.
