Yadong Xu's group from Soochow University proposed a device based on bi-layer meta-gratings that can enable efficiently beam splitting and asymmetric transmission, with obtained results published in Chinese Optics Letters Volume 19, Issue 4 (Shi Qiangshi. Recently, the Prof. Among. This paper proposes a hundred-beam-scale LiDAR scheme based on large-field-of-view diffractive beam splitting and a fiber array for echo reception and presents an in-depth investigation of the angular nonuniformity of diffractive beam splitting and the microradian-scale alignment for such. A fiber-optic splitter, also known as a beam splitter, is based on a quartz substrate of an integrated waveguide optical power distribution device, similar to a coaxial cable transmission system. The optical network system uses an optical signal coupled to the branch distribution., 50/50 FBS, can be used as the frequency-mode Hadamard gate for frequency-encoded photonic qubits.
