Crosstalk in 1.5- mu m InGaAsP optical amplifiers

Crosstalk in 1.5-pm InGaAsP Optical Amplifiers

A dynamical model for multichannel amplification by near-traveling-wave optical amplifiers is presented, and results on crosstalk induced by either amplitude modulation or frequency modulation are given. The mechanisms influencing the crosstalk are especially the residual facet reflectivities and the detuning of the channels relative to the amplifier Fabry-Perot spectrum. Calculations of worst ...

Detailed Dynamic Model for Semiconductor Optical Amplifiers and Their Crosstalk and Intermodulation Distortion

An advanced dynamic model for multisection semiconductor optical amplifiers is Presented. It accounts for the carrier and field distributions in the longitudinal direction as well as for the facet reflectivities. The model can handle arbitrary time-varying input signals and current modulations. Here the model is used to assess intermodulation distortion and crosstalk. First, cascaded amplifiers...

Optical Fiber Amplifiers-Review

This paper reviews optical fiber amplifiers such as Erbium doped fiber amplifiers EDFAs, many types of Raman amplifiers RAs, Thulium doped fiber amplifiers, Tellurite-based fiber Raman amplifiers, semiconductor optical amplifiers and fiber optic parametric amplifiers, principle of operation and construction. As these amplifiers are used for optical fiber communication projects so we shall go th...

Using Semiconductor Optical Amplifiers

Semiconductor optical amplifiers are used for efficient wavelength conversion up to 4 Gb / s. The rise and fall time as well as extinction ratio are experimentally analyzed. System performance at 4 Gb / s is evaluated showing a penalty of only 1.5 dB for the converted signal for conversion over 17 nm.
