Optical distribution networks : signal - to - noise ratio optimization and distributed erbium - doped fiber amplifiers
Two important issues related to the use of remotely-pumped erbium-doped fiber amplifiers in optical distribution networks are analyzed. We investigate the optimal allocation of gain and loss among the stages of a lumped amplifier chain, using the concepts of a Nash solution and Pareto optimality. The propagation of optical channels along an erbium-doped fiber is derived from basic physical cons...
متن کاملCMOS Compatible High Power Erbium Doped Distributed Feedback Lasers
On chip, high power (75mW), erbium-doped distributed feedback lasers are demonstrated in a CMOS compatible fabrication flow. The laser cavities consist of silicon nitride waveguide and grating features defined by wafer-scale immersion lithography and a top erbiumdoped aluminum oxide layer deposited as the final step in the fabrication process. 2013 Optical Society of America OCIS codes: (130.0...
متن کاملModified Split-Step Fourier Method for the Numerical Simulation of Soliton Amplification in Erbium- Doped Fibers with Forward Propagating Noise
Using a modified version of the split-step Fourier method, we analyze the effect of noise on soliton propagation inside erbium-doped fiber amplifiers. In fact, noise from forward-propagating amplified spontaneous emission, associated with a Markov immigration process, is included in the analysis of soliton amplification. Moreover, this algorithm accounts for the real spectral gain profile of th...

متن کاملChirped pulse amplification in an erbium-doped fiber oscillator/ erbium-doped fiber amplifier system OPTICS COMMUNICATIONS
As in bulk amplifiers, the onset of nonlinear effects when amplifying ultra-short pulses in fiber amplifiers has been pointed out and investigated by several groups, specifically in erbium-doped fiber amplifiers ( EDFAs) [ l-3 1. Researchers have in fact used the Kerr nonlinearity in conjunction with group velocity dispersion in order to create even shorter pulses via higher-order soliton forma...
