Design and research of reconfigurable wireless optical communication link based on tunable laser

Abstract

Flexible and reconfigurable communication networks are an important part of an efficient data center. This paper proposes a reconfigurable wireless optical communication link system based tunable laser suitable for connecting data center communication networks. The link system consists of a tunable laser, an optical system, a reflecting mirror, and a photoelectric detection module. A tunable laser that emits multiple wavelengths of laser beams and the corresponding optical system realizes large-angle coverage of the optical link, and at the receiving end, the optical link between different users is constructed by selecting different wavelengths through a band-pass optical filter, realizing flexible, reconfigurable wireless optical communication link system.
