In this review paper some recent advances on optical fiber sensors are reported. In
particular, fiber Bragg grating (FBG), long period gratings (LPGs), evanescent field and …

We propose and demonstrate the cascaded multi-wavelength mode-locked erbium-doped
fiber laser (EDFL) based on ultra-long-period gratings (ULPGs) for the first time, to the best …

Selection of operating wavelength of the Yb‐doped fiber‐ring lasers using long‐period fiber
gratings (LPFGs) is proposed. In the proposed method, customized LPFG that sustains high …

ABSTRACT A novel time-domain ultra-fast pulse shaping approach for multi-TBaud serial
optical communication signal (eg QPSK and 16-QAM) generation based on the first-order …

A novel, all-optical design for implementing terahertz (THz) bandwidth real-time Hilbert
transformers is proposed and numerically demonstrated. An all-optical Hilbert transformer …

This study presents a new process using inductively a coupled plasma dry etching method
to manufacture a long-period fiber grating filter with exact period, vertical sidewalls, and …

A superluminal space-to-time mapping process is reported and numerically validated in
grating-assisted (GA) co-directional couplers, eg fiber/waveguide long-period gratings …

ABSTRACT A relatively simple and cost-effective method to realise a novel long-period fibre
grating (LPFG) based on blue phase liquid crystal (BPLC) composites was proposed and …

A novel design of THz-bandwidth all-optical arbitrary-order temporal differentiators using
long period fiber/waveguide gratings (LPGs) is proposed and numerically demonstrated …

In this work, we provide an up to date overview on the subject of photonic fractional signal
processing, including both, in-fiber and waveguide on-chip technology. Thus, we discuss in …
