Fiber-bragg-grating-based dispersion-compensated and gain-flattened raman fiber Amplifier

Temperature Compensated Fiber Bragg Grating Accelerometer

Following the fast developments that have been taking place in fiber-optic (FO) sensing technology, commercial FO accelerometers are just now reaching the market. Solutions based on Fiber Bragg grating (FBG) technology are the ones that show the greater potential of responding to market demands for FO accelerometers, driven, in part, by some of the valuable characteristics of FO sensors, such a...

Broadband fiber Bragg grating with channelized dispersion.

We present here a new class of multi-channel Fiber Bragg grating (FBG), which provides the characteristics of channelized dispersion but does so with only a single reflection band. An FBG of this type can provide pure phase control of the spectral waveform of optical pulses without introducing any deleterious insertion-loss-variation. We anticipate that this new class of FBG will find some appl...

Raman Amplifier with Integrated Dispersion-Compensating Fiber

It has been more than 20 years since fiber-optic communication became practicable, and there has been a continuing stream of technological breakthroughs. The increased diffusion of the Internet has seen the rapid introduction of dense wavelength division multiplexing (DWDM) systems. With the burgeoning increases in communications capacity in recent years 1), attention has been focused on Raman ...

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...
