Abstract |
: |
The paper reports on analysis of the dyn amics and operation
stability of pumping sem iconductor lasers of optical fiber amplifiers in optical
eornmunication systems. The parameters of the amplifier system that correspond
10 stable operalion and low intensity noise arc explored. The study is based on a
time-delay model of the rate equations of the photon number, optical phase and
the injected electron number. The analyses are performed in terms of the
instantaneous fluctuations of the laser intensity, the corresponding bifurcation
diagram and phase portraits. and the relative intensity noise, The frequency
spectra of the intensity noise under strong feedback are characterized . The results
indicate that the laser stability improves when the length of the external cavity
formed between the laser and a fiber grating decreases where the laser operates
almost in either pulsation or cont inuous wave. The operation becomes almost
chaotic interrupted by narrow regi ons of continuous wave in the extreme of long
external cavities, which degrades the laser stahiliry. |
