In this work, a method is proposed and demonstrated for fabrication of chirped fiber Bragg
gratings (CFBGs) in single-mode fiber by femtosecond laser point-by-point inscription …

Photorefractive materials, including traditional electro-optic photorefractive crystals as well
as photopolymers and photosensitive glasses, have demonstrated their potential in …

We demonstrated numerically that both the chromatic dispersion and the dispersion slope
can be compensated by using purely phase-sampled superstructure fiber Bragg gratings …

The management of chromatic dispersion is one of the challenges of emerging
communication systems. Although chromatic dispersion helps minimizing the non-linear …

A new optical filter architecture is proposed that employs optical subband and all-pass filters
but circumvents the typical tradeoff between passband width and peak delay inherent to all …

We analyze sampled fiber Bragg gratings that have chirp in the grating period, in the
sampling function, or in both. In the last-named case the sampling period can be chirped, the …

We present a detailed study of spectral self-imaging phenomena, namely, integer and
fractional Talbot effects, observed in the reflection response of chirped sampled fiber Bragg …

A novel technique is proposed for refining the spectral regulation of chirped fiber Bragg
gratings (CFBGs) during the fabrication process, utilizing an ultraviolet (UV) laser with a …
