Theoretical investigation on Raman Fiber Amplifiers
Asia Communications and Photonics Conference and Exhibition, 2010The characterization of RFAs with bi-directional Raman pumped or co-propagating Raman pumped is studied. The effection to RFAs for pump power, initial signal power and fiber length is analyzed, which is to optimize and improve gain of RFASSs, so as to improve the performance of the amplifier.

2006 Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference, 2006
This study presents the principles behind a fiber parametric amplifier (FPA) operation. This includes the discussion of parametric amplification, four-wave mixing, phase conjugation, wavelength conversion, and optical regeneration due to gain saturation. FPA applications for quantum-optical systems and optical processing are also discussed.

Polymer optical fiber amplifiers
2012 14th International Conference on Transparent Optical Networks (ICTON), 2012We develop Europium complexes and are now integrating them covalently into the polymer chains of PMMA. Monomer free polymer preforms are prepared, from which optical fibers are drawn. Our aim is to use these fibers as optical amplifiers at about 614 nm for in-house communication systems.

Summary form only given. Wavelength-division multiplexing (WDM) transport networks require amplifiers allowing large channel counts along with large span distances. This means that high gain (>25 dB) and large output power is required, along with low noise figure, in order to ensure high channel signal-to-noise ratio. Hence, for a 2.5-Gbit/s line-rate,

We report a novel vector model of Raman amplification in a fiber with randomly varying birefringence and unidirectional spin profile. Based on this model, we demonstrate for the first time simultaneous mitigation of polarization mode dispersion and polarization dependent gain.

One of the most important technical advances in fiber optic telecommunication systems has been the optical fiber amplifier (OFA). The use of an all-optical fiber optic amplifier instead of a semiconductor optical amplifier has many inherent advantages.
