Abstract
"SISTEMA DE TRANSMISSãO óPTICA, MODULADOR óPTICO RESSONANTE, E, ESTRUTURA DE ELETRODO PARA UM MODULADOR óPTICO" Um modulador óptico ressonante inclui um substrato eletro-óptico, um guia de onda óptico, formado no substrato e tendo um índice variável de refração, e um eletrodo modulador ativo formado sobre o substrato em relação ao guia de onda para efetuar variação eletro-óptica do índice de refração na aplicação ao eletrodo de um sinal modulante. Uma porta de interface formada sobre o substrato fornece o sinal modulante ao eletrodo de uma fonte de sinal e tem uma impedância. Uma estrutura elétrica, formada sobre o substrato e acoplada à porta de interface e ao eletrodo, faz uma impedância do modulador óptico substancialmente igual à impedância da fonte de sinal. A estrutura elétrica inclui uma linha de atraso e fragmento formado sobre o substrato."OPTICAL TRANSMISSION SYSTEM, RESONANT OPTICAL MODULATOR, E, ELECTRODE STRUCTURE FOR AN OPTICAL MODULATOR" A resonant optical modulator includes an electro-optical substrate, an optical waveguide, formed on the substrate and having a variable refractive index, and a variable index of refraction. active modulator electrode formed on the substrate in relation to the waveguide to effect electro-optical variation of the refractive index when applying a modulating signal to the electrode. An interface port formed on the substrate provides the modulating signal to the electrode of a signal source and has an impedance. An electrical structure, formed on the substrate and coupled to the interface port and the electrode, makes the impedance of the optical modulator substantially equal to the impedance of the signal source. The electrical structure includes a delay line and fragment formed on the substrate.
