Image-Recognition Assisted Infrared Femtosecond Laser Direct-Writing Method for Silica Fiber Bragg Gratings

Not Accessible

Your library or personal account may give you access

Abstract

We present a highly reproducible fiber Bragg grating (FBG) fabrication approach using IR femtosecond laser direct-writing method with the assistance of image-recognition technique for automatically positioning grating microstructure inside fiber core.
