A new technique to design an all-fiber temporal differentiator that has a large bandwidth and
an arbitrary differentiation order is proposed and investigated. The proposed temporal …

In this paper, we review our recent developments in the design and fabrication techniques
for high-channel-count fiber Bragg gratings (FBGs). We have presented a theory for the …

We consider an approach to designing complex multichannel filters for ultrabroadband
applications. In contrast to earlier approaches that are restricted to specific problems, our …

A simple method enabling to generate a stable and controllable phase shift in a linearly
chirped fiber Bragg grating (FBG) is theoretically and experimentally demonstrated, which is …

The passage of an optical pulse through a resonant grating is considered. The conditions
under which the resonant grating differentiates the envelope of the incident pulse are …

This work addresses the tailoring spectral response of grating-assisted co-directional
couplers (GADCs) in the context of wavelength filtering for fiber-to-the-home (FTTH) …

A double sampling method enabling to have excellent channel uniformity and high in-band
energy efficiency is firstly proposed for the design of an ultrahigh-channel-count fiber Bragg …

We propose an advanced genetic algorithm (GA) to design fiber Bragg gratings (FBGs) with
given fabrication constraints. Our GA is enhanced by a new Fourier-series-based real …

We have proposed an effective method to synthesize and optimize multichannel fiber Bragg
grating filters (MCFBGFs). The novel method contains two steps, ie, the discrete layer …

The discrete layer-peeling algorithm (DLPA) requires to discretize the continuous medium
into discrete reflectors to synthesize nonuniform fiber Bragg gratings (FBG), and the …
