A Proposal for a New Method of Modeling of the Quantum Dot Semiconductor Optical Amplifiers
With the advancement of nanoscale semiconductor technology,semiconductor optical amplifiers are used to amplify and process all-optical signals. Inthis paper, with the aim of calculating the gain of quantum dot semiconductor opticalamplifier (QD-SOA), two groups of rate equations and the optical signal propagatingequation are used in the active layer of the device. For t...
متن کاملUsing 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.
متن کاملBroadband fiber optical parametric amplifiers.
The bandwidth of a single-pump fiber optical parametric amplifier is governed by the even orders of fiber dispersion at the pump wavelength. The amplifier can exhibit gain over a wide wavelength range when operated near the fiber's zero-dispersion wavelength. It can also be used for broadband wavelength conversion,with gain. We have experimentally obtained gain of 10-18 dB as the signal wavelen...
متن کاملSemiconductor Optical Amplifiers in WDM Tree-Net
In this paper, effectiveness of semiconductor optical amplifiers (SOA's) in tree-net in terms of increase in the number of users has been investigated. In the analysis, SOA's with i) unsaturated gain, ii) average gain saturation, and iii) average gain saturation with gain fluctuations have been considered. Further, the results for the tree-net are compared with those for the star network. It is...
متن کاملSelf-Phase Modulation in Semiconductor Optical Amplifiers
This paper presents a detailed theoretical and experimental study of the impact of amplified spontaneous emission (ASE) on self-phase modulation in semiconductor optical amplifiers (SOAs). A theoretical model of pulse propagation in SOAs is developed that includes the ASE power and its effect on gainsaturation and gain-recovery. We study the impact of ASE on the nonlinear phase shift, frequency...
