High-Efficiency, Wide Working Bandwidth Antenna Based on SOI Platform for Optical Phased Array
A novel structure of a subwavelength surface optical antenna for optical phased array is proposed in this paper. An asymmetric vertical grating structure is applied to achieve high emission efficiency (73% at 1550 nm). Optical antennas with large fabrication tolerances can also maintain a wide worki...
