“…The semiconductor optical amplifier (SOA) is a promising device for regeneration and reshaping (2R) of optical pulsed signals after its degradation [1,2] for wavelength conversion [3,4] and for optical switching [5]. Several 2R regeneration techniques based on the SOA have been proposed and tested, for example by using four-wave mixing [6], cross-gain modulation (XGM) [7][8][9], integration within Mach-Zehnder interferometer (MZI) [10,11], cross-phase modulation with filtering (XPM) [12], cascaded SOAs [13], and feed forward technique [14]. Most of these techniques require complex designs and/or involve critical operation points, even some of the simplest ones based on XGM features [7].…”

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.

“…This technique requires considerable computational effort, and it is very time consuming. The alternative methods [5][6][7][8][9][10][11][12][13][14][15][16] for the determination of resonant frequency are reported for regular shape (rectangular, square, triangular, circular, semi-circular) microstrip patch antennas.…”

“…Diversas técnicas para regeneração 2R (reamplificação e reformatação) baseadas em SOA têm sido propostas e testadas, como, por exemplo, usando: mistura de quatro ondas (FWM-four-wave mixing) [3], modulação cruzada de ganho (XGM -cross-gain modulation) [4], integração com interferômetro de Mach-Zehnder (MZI-Mach-Zehnder interferometer) [5], ou modulação cruzada de fase (XPMcross-phase modulation) [6]. A maioria dessas técnicas requer complexas implementações e/ou envolve pontos críticos de operação, mesmo nos casos mais simples baseados no efeito XGM [4].…”

Resumo -Um conversor em comprimento de onda baseado no efeito XGM utilizando apenas um amplificador óptico a semicondutor é apresentado. Este conversor apresenta boa capacidade de regeneração (1<ΔQ<4,5) para taxas de 0,6 a 13,5 Gbps. A caracterização foi realizada para sinais com modulação NRZ, incluindo testes no enlace de fibras do projeto KyaTera/FAPESP.Palavras-chaves -Amplificador óptico a semicondutor, amplificadores ópticos, óptica não-linear, regeneração óptica.

We present a novel characterization method for semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) switches which combines a pump-probe measurement with an interferometer bias scan. In addition to a wealth of information on the switching dynamics for all operating points of the switch, we can create an extinction map to pinpoint regions of highest extinction for optimizing all-optical ultrafast switching. We experimentally verify the accuracy of this characterization method by performing a wavelength characterization at the optimal bias point and a nearby, non-optimal point. A 1-dB penalty was observed.
