We investigate the relationship of negative feedback signal intensity with bit error rate using optical triode. It was found out that power penalty was improved by 15 dB and noise suppression characteristic was obtained.
We address design and optimization of optical filters for spectrum-sliced wavelength division multiplexed (SS-WDM) systems employing saturated semiconductor optical amplifiers (SOAs) to suppress intensity noise. We study the impact of the shape of both slicing and channel selecting optical filters vis-a-vis two important impairments: the filtering effect and the crosstalk. The quantification of bit...
Bit-error rate (BER) estimations are presented for an all-optical regenerator with wavelength conversion using just one semiconductor optical amplifier (SOA) by means of the cross gain modulation (XGM) in a counter-propagation mode. The extinction ratio (ER) degradation and the quality (Q) factor improvement obtained by the regenerator are analyzed, and good experimental performances were achieved...
