【 中文摘要 】
本发明公开了一种1×N光开关结构，涉及光通信技术和光传感技术领域，包括多个开关单元；第M列的每个开关单元的输出端口均连接有多级隔离单元；开关单元为第一1×2开关单元或常规1×2开关单元，第一1×2开关单元不被控制时，输出端口的分光比例为X％和Y％；隔离单元为第一1×1隔离单元或常规1×1隔离单元，第一1×1隔离单元不被控制时，输出端口的输出光功率比例为A％；光开关不被控制时，光从第一列的开关单元的输入端口输入，从包含第一1×1隔离单元的多级隔离单元的输出端口输出。本发明的光开关结构能够在对光开关不进行控制时，直接使用光功率监测的方式，完成输入端口及输出端口之间与光纤或者其它光学元件的耦合。
【 英文摘要 】
The invention discloses a 1xN optical switch structure, which relates to the field of optical communication technology and optical sensing technology, and includes multiple switch units; the output port of each switch unit in the Mth column is connected to a multi-stage isolation unit; the switch unit is a first 1 × 2 switch unit or a conventional 1 × 2 switch unit. When the first 1 × 2 switch unit is not controlled, the light splitting ratio of the output port is X% and Y%; the isolation unit is the first 1 × 1 isolation unit or a conventional 1 × 1 isolation unit. When the first 1 × 1 isolation unit is not controlled, the output optical power ratio of the output port is A%; when the optical switch is not controlled, light is input from the input port of the switch unit in the first row and output from the output port of the multi-stage isolation unit including the first 1x1 isolation unit The optical switch structure of the present invention can complete the coupling between the input port and the output port and the optical fiber or other optical elements by directly using the optical power monitoring method when the optical switch is not controlled.
