Biaxial 3D-Printed Inclinometer Based on Fiber Bragg Grating Technology

Temperature-Independent Fiber Inclinometer Based on Orthogonally Polarized Modes Coupling Using a Polarization-Maintaining Fiber Bragg Grating

A reflection fiber inclinometer is proposed and experimentally demonstrated based on two linearly polarized (LP) modes coupling. The configuration consists of a section of polarization-maintaining fiber (PMF) containing a fiber Bragg grating (FBG) splicing with single mode fiber (SMF). Bending the PMF in the upstream of FBG can induce an additional birefringence of PMF, which results in the int...

Fiber-Bragg-Grating Based Optical Amplifiers

In this chapter, we propose several schemes for fiber amplifiers which are all using fiber Bragg gratings (FBGs) as the key elements for their advantages of better uniformity, higher contrast ratio and lower cost. Several applications using FBG-based fiber amplifiers are also introduced. Therefore, this chapter initiates the overview of FBGs characteristics in Sec. 1, then addresses the FBGs pl...

Fiber Bragg Grating Technology for New Generation Optical Access Systems

Thanks to achievements in photonics technologies optical networks have gained a notably increase in capacity per single fiber during the last decade [1]. Demand for greater transmission speed has been increasing exponentially because of the impulsive spread of Internet services (see Fig. 1) [2]. At the same time, the radical improvement of the capability of digital technologies has made feasibl...

Microwave photonic integrator based on a multichannel fiber Bragg grating.

We propose and experimentally demonstrate a microwave photonic integrator based on a multichannel fiber Bragg grating (FBG) working in conjunction with a dispersion compensating fiber (DCF) to provide a step group delay response with no in-channel dispersion-related distortion. The multichannel FBG is designed based on the spectral Talbot effect, which provides a large group delay dispersion (G...
