TL;DR: In this paper, a new class of long-period fiber gratings that can be used as in-fiber, low-loss, band-rejection filters is presented.
Journal ArticleDOI
Long-period fiber-grating-based gain equalizers.
Ashish Madhukar Vengsarkar,J. Renee Pedrazzani,J. B. Judkins,Paul Joseph Lemaire,Neal S. Bergano,C. R. Davidson +5 more
TL;DR: Long-period fiber gratings are used to f latten the gain spectrum of erbium-doped fiber amplifiers and it is shown that a chain of amplifiers can be equalized, leading to a bandwidth enhancement by a factor of 3.

Long-period fiber gratings as band-rejection filters
Ashish Madhukar Vengsarkar,Paul Joseph Lemaire,J. B. Judkins,Vikram Bhatia,Turan Erdogan,John E. Sipe +5 more
TL;DR: In this paper, a novel class of photoinduced, long-period fiber gratings that function as highly-efficient band-rejection filters is presented, which can be used for some of the applications.
