Abstract

"DISPOSITIVO ACúSTICO-óPTICO DE PASSAGEM DUPLA, GERADOR DE LASER SINTONIZáVEL, E, PROCESSO PARA FILTRAGEM DE UMA FREQuêNCIA óPTICA". Um dispositivo acústico-óptico de passagem dupla incluindo um comutador acústico-óptico possuindo uma primeira região de conversão de polarização conectada entre as primeiras portas de entrada e saída, e uma segunda região de conversão conectada entre as segundas portas de entrada e saída; e uma combinação óptica conectada entre a primeira porta de saída e a segunda porta de entrada através de fibras ópticas e incluindo um elemento de isolamento óptico. O dispositivo acústico-óptico de passagem dupla pode alternativamente incluir um comutador acústico-óptico incluindo uma região de conversão de polarização única conectada entre as primeiras portas de entrada e saída e também conectada entre as segundas portas de entrada e saída. Um filtro de passagem de banda, um filtro de entalhe, e soma/eliminação e um gerador de laser sintonizável podem ser formados utilizando o dispositivo acústico-óptico."DOUBLE-PASS ACOUSTIC-OPTICAL DEVICE, TUNNABLE LASER GENERATOR, AND PROCESS FOR FILTERING AN OPTICAL FREQUENCY". A double-pass acoustic-optical device including an acoustic-optical switch having a first polarization conversion region connected between the first input and output ports, and a second conversion region connected between the second input and output ports; and an optical combination connected between the first outlet port and the second port of entry through optical fibers and including an optical isolation element. The double-pass acoustic-optical device may alternatively include an acoustic-optical switch including a single polarization conversion region connected between the first input and output ports and also connected between the second input and output ports. A bandpass filter, a notch filter, and sum / elimination and a tunable laser generator can be formed using the acoustic-optical device.
