Abstract

Patente de Invenção para <B>"SUPRESSãO DE DIFUSãO DE BRILLOUIN ESTIMULADA EM FIBRA óTICA"<D>. Supressão de difusão de Brillouin estimulada (SBS) pela ampliação do espectro de energia de fótons de SBS de participação e/ou fonos é alcançada em uma fibra ótica tendo um núcleo com ambos perfis de viscosidade e de CTE radialmente não-uniformes, pela alternação de camadas de dopantes de modificação de vidro, tal como fósforo e flúor. Os perfis de expansão térmica não-uniforme e de viscosidade concedem uma tensão não-uniforme pemanente residual na fibra. O efeito de supressão da SBS proporcionado pela tensão não-uniforme, pode ser controlado e intensificado pela aplicação de uma força de tensão uniforme e não-uniforme à fibra a medida que ela está sendo estirada. Uma pré-forma para a fibra é também revelada.
