“…The BER tests were not performed as 2R regenerators such the one presented can be adequate to maintain signal quality over short and medium distances, where noise and distortion are small. For long distances applications, the jitter accumulation requires a 3R regeneration with clock recovery [20], and BER tests are strictly necessary.…”

A simple all-optical cross-gain modulation (XGM) wavelength conversion scheme based on a single semiconductor optical amplifier with higher regeneration capabilities is presented. A proof of concept was performed at data rates from 0.6 to 13.5 Gbps for NRZ streams using the KyaTera/FAPESP buried fiber optical testbed. Good results were obtained for large lambda-detuning (>10 nm), including conversion to the same wavelength. The best experiments achieved an improvement in the quality factor (Q-factor) over 4 units with input signals deteriorated by the standard fiber dispersion, with an extinction ratio penalty of 1.5 dB. In addition, the converter presented a small dependence with the relative optical input signal polarization (around 1 dB). Figure 1 All optical 2R-conversion scheme divided in blocks: single-SOA in counter-propagation mode ABSTRACT: A generalized method is presented to determine the resonant frequency of slot-loaded rectangular microstrip patch antenna by equating its area to an equivalent area of a rectangular microstrip patch antenna. The computed results are in good agreement with the reported simulated and measured results.

An efficient optical signal regenerator can mitigate the effect of signal degradation and increase the performance of optical communication system. All optical signal regenerators have been studied and developed for maintaining good quality signal in long haul optical communication. Fiber nonlinearity has some inherent properties for signal regeneration and it has an enormous potential for ultra-high speed optical communication. In this paper, all optical signal regeneration techniques using self-phase modulation (SPM) are examined. Major drawbacks of the existing regenerators have also been identified.

“…All-optical reamplification, reshaping, and retiming (3R) regeneration can be achieved using non-linear optical gates, among other options [1,2]. A non-linear optical gate of a 3R regenerator is a three-port gate, where one port is fed by a decision signal, another port by a clock signal obtained from a clock recovery device (CRD), and the regenerated signal is obtained in the third port.…”

The impact of the switching window shape on the performance of a chain of reamplification, reshaping, and retiming all-optical regenerators based on a nonlinear gate is investigated numerically. A method to estimate the chain performance that considers the amplitude fluctuations due to timing jitter and noise redistribution along the chain is proposed. The results show that the rectangular switching window is not appropriate for reamplification, reshaping, and retiming regenerators, and the optimum shape of the switching window depends on the number of regenerators of the chain, optical noise power, and timing jitter levels.
