Abstract

APARELHO DE COMUTAÇÃO ÓPTICA, MÉTODO DE REDIRECIONAMENTO, MULTIPLEXADOR DE INSERÇÃO/DERIVAÇÃO ÓPTICO RECONFIGURÁVEL, E SISTEMA. A presente invenção refere-se a aparelho de comutação óptica, método de redirecionamento, multiplexador de inserção/derivação óptica reconfigurável e sistema (2400), os quais são usados para aumentar a largura de banda de filtro. compreendendo porta de entrada (41), componente de dispersão, primeiro filtro (311), componente de redirecionamento (301) e portas de saída (42 e 43); a porta de entrada (41) é usada para incidir primeiro e segundo feixes de luz (710, 720) sobre o componente de dispersão, que é usado para decompor o primeiro feixe de luz (710) em pluralidade de primeiros subfeixes (401), ainda usado para decompor o segundo feixe de luz (720) em pluralidade de segundos subfeixes (402); as pluralidades de primeiros e de segundos subfeixes (401, 402) pertencem a diferentes bandas. O primeiro filtro (311) é usado para separar as direções de transmissão das pluralidades de primeiros e segundos subfeixes (401, 402) em primeira direção (X) em diferentes direções de transmissão com base em diferentes bandas, e incidir a pluralidade de primeiros e segundos subfeixes (401, 402) sobre primeira e segunda região (501, 502) do componente de redirecionamento (301), onde as primeira região e segunda regiões (501, 502) são separadas uma da outra ao longo da primeira direção (X).
