A Chirped Fiber Bragg Grating with Ripple Free Group Delay and its Application in Laser Ranging

Not Accessible

Your library or personal account may give you access

Abstract

The group delay ripple (< +/−50ps) of a chirped fiber Bragg grating (dispersion = 1651ps/nm) is removed by spectral phase modulation to achieve twofold improvement in the range resolution (~320µm) of a chirped pulse lidar.
