            doped nonlinear waveguides

Erbium-doped fiber devices have been extraordinarily successful due to their broad optical gain around 1.5-1.6 μm. Er-doped fiber amplifiers enable efficient, stable amplification of high-speed, wavelength-division-multiplexed signals, thus continue to dominate as part of the backbone of longhaul telecommunications networks. At the same time, Er-doped fiber lasers see many applications in telecommunications as well as in biomedical and sensing environments. Over the last 20 years significant efforts have been made to bring these advantages to the chip level. Device integration decreases the overall size and cost and potentially allows for the combination of many functions on a single tiny chip. Besides technological issues connected to the shorter device lengths and correspondingly higher Er concentrations required for high gain, the choice of appropriate host material as well as many design issues come into play in such devices. In this contribution the important developments in the field of Er-doped integrated waveguide amplifiers and lasers are reviewed and current and future potential applications are explored. The vision of integrating such Er-doped gain devices with other, passive materials platforms, such as silicon photonics, is discussed.

“…Nos últimos 10 anos, a não linearidade dos meios dopados com Érbio tem atraído grande interesse, e tem sido recentemente explorada para o projeto de diversos dispositivos, tais como chaves ópticas [1], sensores [2] e para o processamento de sinais ópticos [3]. Nos trabalhos presentes na literatura, as atenções tem sido voltadas ora para as variações do índice de refração em função da intensidade do campo do bombeio (não linearidade induzida pelo campo do bombeio) [4,5], e ora para as variações do índice de refração em função da intensidade do campo do sinal (não linearidade induzida pelo campo do sinal) [6].…”

Uma análise comparativa entre as não linearidades induzidas pelas intensidades dos campos do sinal e bombeio em meios dopados com Érbio são apresentadas neste trabalho. Os resultados são obtidos através da modelagem da susceptibilidade complexa, em que são considerados a intensidade e o comprimento de onda dos campos eletromagnéticos envolvidos, assim como os efeitos de altas concentrações de Érbio. O uso de múltiplas lorentzianas permite a análise dentro da faixa do espectro de 1.44µm até 1.60µm. Os resultados mostram que os coeficientes da expansão da variação do índice de refração em função da intensidade do sinal (≈ 1.5µm) são de até duas ordens de grandeza maiores que daqueles calculados em função da intensidade do bombeio(≈ 0.98µm).

A numerical analysis for erbium‐doped tellurite‐based fiber amplifiers (EDFA) is presented for the first time in the literature. Modal and propagation equations are solved using the finite‐element method and the Runge–Kutta algorithm, respectively, and are applied to a homogeneous four‐level erbium‐doped fiber pumped at 1480 nm. Energy transfer due to cooperative up‐conversion, cross relaxation, and excited state absorption is considered here. Comparisons with published experimental data confirm the present theoretical results. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 103–107, 2000.
