Abstract
一种1×N光波分多路分用器校准装置包括:一包含输入波导、N个输出波导和多个位于输入和输出波导周围的校准波导的1×N光波分多路分用器;一单光纤块;一多重光纤块;一测量部分及一控制器。在校准1×N光波分多路分用器期间,由于具有位于通讯波长区之外的波长的光被输出到1×N光波分多路分用器的波导的外面,由此实现不依赖于波长的校准。因此,可快速和容易地实现光纤和光学装置之间的校准和粘合,且系统的结构被简化。
Description
本发明涉及用于使用波分多路分用耦合器的1×N光波分多路分用器的校准装置,更具体的涉及用于通过在1×N光波分多路分用器的外部提供校准波导校准光波分多路分用器和光纤块的设备。
对诸如光波分多路分用器的光波导装置的校准在生产光波导器件中属于作为结束步骤的封装过程。为了提高生产效率,通过用光纤容易地校准器件对缩短在光波导器件和光纤之间的连接时间是很重要的。
为了将光波导型器件芯片安装到网络中,必须进行校准和与光纤的黏结。
图1A示出了传统的1×N光波分多路分用器的示意图,例如1×8光波分多路分用器。而图1B示出了传统的用于与图1A中所示的1×8光波分多路分用器的输出侧进行校准的传统的光纤块。
在光源(未示出)中产生的光被入射到输出光纤中,然后与图1A中所示的光波分多路分用器的输入波导100进行校准。光波分多路分用器的输出波导102被与图1B中所示的光纤块进行校准以使光被导引。在测量从光纤块的两个最外接口输出的光的强度的同时通过精细地调节光纤和光波分多路分用器的位置可精确地确定最大的导引光的位置,然后光纤和光波分多路分用器在所确定的位置被用环氧树脂粘合。
诸如光波分多路分用器的光学设备具有波长的特性。因此,为了在光波导器件和光纤块之间实现校准和粘合,需要确定可进行精确校准和获得满意波长特性的最佳的位置。
对于为此光波导器件所生产的芯片的波长特性可能会不同。因此,需要在校准和粘合之前知道精确的波长特性。相应的,需要多个用于产生不同波长的光源。因此,系统会变得复杂并需要大量的构件。
为了解决上述的问题,本发明的目的是提供一种用于1×N光波分多路分用器的校准装置,用于通过向位于光波分多路分用器外部的校准波导输出波长位于通讯区外的光而进行与波长无关的校准,从而校准光波分多路分用器和光纤块。
相应的,为了实现上述的目的,所提供的1×N光波分多路分用器校准装置包括:一个包含输入波导、N个输出波导和多个位于输入和输出波导周围的校准波导的1×N光波分多路分用器,如果信号光的波长位于通讯波长区内,用于多路分用信号光并将被多路分用的信号光提供到N个输出波导,且如果信号光的波长位于通讯波长区外用于向校准波导提供信号光;一个单光纤块,其具有单光纤,用于向1×N光波分多路分用器发送信号光;一个多重光纤块,其具有与N个波导的输出方相连的N个光纤和与校准波导的输出方相连的校准光纤;一个测量部分,用于测量从校准光纤输出的光的强度;及一个控制器,用于精确地控制单光纤块和校准波导之间的校准及校准波导和多重光纤块之间的校准。
1×N光波分多路分用器还可包含一个波分多路分用耦合器,用于在输入信号光的波长位于通讯波长区内时向输出波导提供信号光,并在输入信号光的波长位于通讯波长区外时向校准波导提供信号光。
通过下面结合相应的附图的描述会对本发明的上述的目的和优点有更清楚的认识。
图1A为传统的1×8光波分多路分用器的示意图;
图1B为在图1A中所示的1×8光波分多路分用器的输出侧用于校准的传统的光纤块的示意图;
图2为根据本发明的使用一个光波分多路分用器的1×N光波分多路分用器校准装置的示意图;
图3为图2中所示的多重光纤块的示意图。
参考图2,1×N光波分多路分用器校准装置包含一个光源200,一个单光纤块210,一个1×N光波分多路分用器220,一个多重光纤块240和一个控制器250。这里N为8。
1×N光波分多路分用器220包括一个波分多路分用(WDM)耦合器221,一个1×N光波分多路分用部分222,一个外部校准波导223和一个内部校准波导224。
图3中示出一个多重光纤块230,并包括一个上体300和一个下体302。下体302包括一个V-形槽304,其中固定有校准光纤303;以及一个V-形槽306,其中固定有与1×N光波分多路分用器220的输出波导相连的N个光纤305。这里,其中用于固定校准光纤303的槽304的数目在1×N光波分多路分用器220除了包含外部和内部校准波导223和224以外还包含弯曲或线形波导的情况下可增加。可用不是由带或线制成的通常的光纤作为校准光纤,在校准或粘合后将其去除。
根据本发明的1×N光波分多路分用器校准装置可按如下方式进行工作。光源200产生波长位于1550nm通讯波长区域内的光。WDM耦合器221将从单光纤块210发送的1550nm波长区域的光提供到1×N光波分多路分用部分222的输出波导。通过WDM耦合器221不将1550nm波长区域的光发送到外部和内部校准波导223和224。
在校准期间,可使用产生位于通讯波长区域以外波长光(例如633nm)的氦氖激光作为光源200。WDM耦合器221将从单光纤块210发送的波长为633nm的校准光提供到外部和内部校准波导223和224。换句话说,由于在WDM耦合器221中不会产生校准光的完全迁移,校准光被提供到外部和内部校准波导223和224。
从第一和第二波导223和224提供的光被通过多重光纤块230的校准光纤输出到测量部分240。这里,输出校准光不必处于高的功率电平。
测量部分240测量从校准光纤输出的的校准光的功率电平。
控制器250调节单光纤块210、1×N光波分多路分用器220和多重光纤块240的位置,使得由测量部分240所测量的校准光的功率电平为最大。
在功率电平变为最大的位置将各个元件粘合,然后去除校准光纤。
根据本发明,在校准1×N光波分多路分用器期间,由于波长位于通讯区域之外的光被输出到1×N光波分多路分用器的外部波导,由此实现了与波长无关的校准,无须知道各个光学器件的精确的波长特性。因此,可实现光纤和光学器件之间的容易和快速的校准和粘合,并且使系统的结构变得简单。
