Chirped fiber grating
WebPhase-inserted fiber gratings (PI-FGs) refer to those gratings where there exist a number of the phase-shifts (spatial spacing) among different sections (or local periods) of the gratings themselves. All the PI-FGs developed to date can mainly be divided into three categories: phase-shifted gratings, phase-only sampled gratings, and phase-modulated gratings, of … WebThe eect of incorporating a fiber Bragg grating (FBG) in long wavelength band erbium-doped fiber laser (L-band EDFL) is investigated. The EDFLs with and without the FBG operate at wavelength of ...
