Description

一种基于VCSEL的CWDM光器件 技术领域
本发明涉及一种波分复用光器件，尤其是指一种基于VCSEL的CWDM光器件。
 背景技术
传统COB（Chip On Board，板载芯片封装）技术，所用的激光多为850nm多模激光，用并行光通信方法实现多路光并行通信。所用的光学器件无法处理波分复用技术，因此单路光通道仅仅是一个波长的通道，无法实现波分复用。另外，传统的CWDM（Coarse Wavelength Division Multiplexing，粗波分复用）技术，所用的激光多为边缘发射半导体激光，且多为单模激光。所用的光器件以及光学系统的装配耦合难度比COB技术高且不容易实现大规模量产，生产成本较高。
 技术问题
本发明所要解决的技术问题是：提供一种基于VCSEL的CWDM光器件，使得COB技术可以与CWDM技术相结合，在板载芯片封装上实现光学的粗波分复用，从而进一步降低波分复用系统的装配难度以及生产成本。
 技术解决方案
为了解决上述技术问题，本发明采用的技术方案为：
本发明提供了一种基于VCSEL的CWDM光器件，其包括：衍射光器件、多个滤波片及多个光透镜，多个所述滤波片分别具有不同的波长，所述衍射光器件一端内置有接收口，多个所述滤波片设置在衍射光器件内且均与接收口共线设置，多个所述滤波片与其安装面之间均呈45°夹角，多个所述滤波片的安装面上开设有多个通孔且分别与多个滤波片的位置对应，多个所述光透镜分别设置在多个通孔中。
进一步的，所述滤波片及光透镜各设置有6个。
进一步的，经过6个所述光透镜的光分别具有不同的波长，且经过6个所述光透镜的光之间的波长间隔小于或等于25nm。
进一步的，6个所述滤波片均为低通滤波片。
进一步的，所述接收口为LC、FC、SC及ST标准单纤光接口中的任意一个。
进一步的，所述衍射光器件内设有滤波片放置槽，所述滤波片放置槽设置在多个滤波片与多个滤波片的安装面之间。
进一步的，多个所述滤波片与滤波片放置槽之间形成有光学胶水胶层。
进一步的，所述基于VCSEL的CWDM光器件还包括基于多路不同波长的VCSEL，所述VCSEL设置在多个光透镜远离多个滤波片一侧，且所述VCSEL发出多路不同波长的光分别经过多个光透镜准直后对应照射到多个滤波片上。
 有益效果
本发明的有益效果在于：多个不同波长的光先分别被多个光透镜准直，对应照射到多个滤波片上，再由多个滤波片将多个不同波长的光均反射成平行的光后到达接收口汇聚成一束光。本发明将多个具有不同波长的滤波片设置在衍射光器件内，能够实现光学系统与COB技术及CWDM技术的结合，从而在板载芯片封装上实现光学的粗波分复用，进一步降低波分复用系统的装配难度以及生产成本。

 本发明的实施方式
为详细说明本发明的技术内容、构造特征、所实现目的及效果，以下结合实施方式并配合附图详予说明。
请参阅图1、图2、图3以及图4，本发明提供了一种基于VCSEL的CWDM光器件，该基于VCSEL的CWDM光器件包括衍射光器件001、多个滤波片002及多个光透镜003，其中多个滤波片002分别具有不同的波长，衍射光器件001一端内置有接收口004，多个滤波片002设置在衍射光器件001内且均与接收口004共线设置，多个滤波片002与其安装面005之间均呈45°夹角，多个滤波片002的安装面005上开设有多个通孔007且分别与多个滤波片002的位置对应，多个光透镜003分别设置在多个通孔007中。
实际工作过程中，多个不同波长的光先分别被多个光透镜003准直，对应照射到多个滤波片002上，再由多个滤波片002将多个不同波长的光均反射成平行的光后到达接收口004汇聚成一束光，以此实现粗波分复用的合成。
需要说明的是，不同波长且集中在一根光纤上的光通过接收口004准直后依次照射在多个滤波片002上，再由多个滤波片002对应反射到多个光透镜003上，以此实现粗波分复用的解复用。
需要进一步说明的是，多个滤波片002是设置在多个光透镜003与接收口004之间的，故粗波分复用的合成和分解不是只能单独进行，即多个光透镜003中，一部分光透镜003可作为粗波分复用合成时不同波长的光进入衍射光器件001使用，而另一部分光透镜003同时可作为粗波分复用分解时不同波长的光穿出衍射光器件001使用，同时接收口004亦可对应设置有多个。
从上述描述可知，本发明的有益效果在于：多个不同波长的光先分别被多个光透镜准直，对应照射到多个滤波片上，再由多个滤波片将多个不同波长的光均反射成平行的光后到达接收口汇聚成一束光。本发明将多个具有不同波长的滤波片设置在衍射光器件内，能够实现光学系统与COB技术及CWDM技术的结合，从而在板载芯片封装上实现光学的粗波分复用，进一步降低波分复用系统的装配难度以及生产成本。

具体的，该基于VCSEL的CWDM光器件还包括基于多路不同波长的VCSEL，VCSEL设置在多个光透镜003远离多个滤波片002一侧，且VCSEL发出多路不同波长的光分别经过多个光透镜003准直后对应照射到多个滤波片002上。
本实施例中，基于多路不同波长的VCSEL用于提供多个不同波长的光，VCSEL发出的不同波长的光通过本发明提供的基于VCSEL的CWDM光器件实现粗波分复用的合成。
综上所述，本发明提供的一种基于VCSEL的CWDM光器件，其有益效果在于：多个不同波长的光先分别被多个光透镜准直，对应照射到多个滤波片上，再由多个滤波片将多个不同波长的光均反射成平行的光后到达接收口汇聚成一束光。本发明将多个具有不同波长的滤波片设置在衍射光器件内，能够实现光学系统与COB技术及CWDM技术的结合，从而在板载芯片封装上实现光学的粗波分复用，进一步降低波分复用系统的装配难度以及生产成本。接收口采用LC、FC、SC及ST中的任意一个标准单纤光接口，可以方便外接光路。滤波片放置槽用于放置多个滤波片，而滤波片放置槽与多个滤波片之间通过光学胶水粘贴在一起，可以使得多个滤波片更加稳固。基于多路不同波长的VCSEL用于提供多个不同波长的光，VCSEL发出的不同波长的光通过本发明提供的基于VCSEL的CWDM光器件实现粗波分复用的合成。
