Global patent analysis of distributed feedback laser

doi:10.12267/j.issn.2096-5931.2022.06.010

Abstract

Abstract:

DFB laser has become one of the most important and widely used light sources in communication system because of its excellent spectral and modulation characteristics. This paper analyzes the global patent distribution of DFB laser from the perspectives of annual application volume, applicant, regional distribution and technical distribution, analyzes and interprets the characteristic patents. Provide information reference for DFB laser research institutions from the perspective of patent.

Key words: distributed feedback laser, DFB, patent

CLC Number:

TN248
