High-efficiency grating couplers for pixel-level flat-top beam generation
Zhong-Tao Tian, Ze-Peng Zhuang, Zhi-Bin Fan +2
We demonstrate a kind of grating coupler that generates high quality flat-top beam with a small beamwidth from photonic integrated circuits into free-space. The grating coupler is…
