Description

technical field [0001] The invention relates to the technical field of semiconductor chips, in particular to a singular point beam transceiver system. Background technique [0002] Singularity optics is considered as a new branch of modern optics, and the object of study is the singularity of the light field. This type of light field can maintain the existence of optical singularity during the transmission process, and the existence of optical singularity will lead to zero intensity of singularity. Optical singularity refers to the point in the light field whose physical parameters cannot be defined, so the light intensity or amplitude of this point must be equal to zero to make it have physical existence. Singularity optics include a phase vortex beam with a phase singularity (Phase Singularity), usually called a vortex beam; a polarized vortex beam with a polarization singularity (Polarization Singularity), usually called a vector beam; Both vector vortex beams. Among t...

AI Technical Summary

Problems solved by technology

They have shortcomings such as large size, difficulty in integration, and complex test system, which seriously limit the application of singularity beams in small-size fields

In addition, the existing singularity beam transmitting and receiving systems are separated, so after the singularity beam is emitted, it is necessary to build a complex test system to determine the characteristics of the beam, which further increases the difficulty of exploring the characteristics of the singularity beam
