 本发明的最佳实施方式
现结合附图，对本发明的较佳实施例作详细说明。
如图1至图3所示，本发明提供一种实现监测发射功率的SR4器件的优选实施例。
具体地，并参考图1，一种实现监测发射功率的SR4器件，所述SR4器件包括用于发射激光的发射组件、用于接收激光的接收组件和用于监测发射组件的发射功率的监测组件30，所述监测组件30即是监测芯片；所述发射组件发射激光到接收组件，所述接收组件接收激光，并且所述监测组件30实时监测发射组件所发射激光的功率。
参考图2，所述发射组件包括发射芯片11、用于全反射激光的第一斜面镜12、用于折射和反射激光的第二斜面镜13、用于准直激光的第一准直透镜14、用于聚焦激光的第一聚焦透镜16和用于聚焦激光的第二聚焦透镜15；所述第一准直透镜14邻近设置于发射芯片11，沿着激光的传输方向，所述第一斜面镜12设置在第一准直透镜14之后，所述第二斜面镜13设置在第一斜面镜12之后，所述第二聚焦透镜15设置在第二斜面镜13和监测组件30之间，并邻近设置于监测组件30，所述第一聚焦透镜16设置在第二斜面镜13和光纤40之间，并邻近设置于光纤40。其中，所述第一斜面镜12为平面反射镜，保证对激光能够实现全反射。其中，所述第一斜面镜12呈一设定角度，使发射芯片11的发射激光在反射时候能够全面反射；由于SR4器件的内部构造，所述第一斜面镜12与第二斜面镜13的角度相配合，使激光水平朝向光纤传输，保证光路能够耦合。
参考图3，所述接收组件包括用于全反射并聚焦的第三斜面镜21、接收芯片22、用于准直激光的第二准直透镜23、用于聚焦激光的第三聚焦透镜24和用于准直激光的第三准直透镜25；所述第二准直透镜23邻近设置于光纤40，沿着激光的传输方向，所述第三斜面镜21设置在第二准直透镜23之后，所述第三聚焦透镜24设置在第三斜面镜21和接收芯片22之间，位于第三斜面之后，所述第三准直透镜25设置在所述第三聚焦透镜24和接收芯片22之间，位于第三聚焦透镜24之后。其中，所述第三斜面镜21为球面反射镜，保证在反射激光的同时对激光进行聚焦，激光聚焦后传输至第三聚焦透镜24，避免激光溢出通光孔径。
其中，所述发射组件的光路传输如下述：所述发射芯片11向第一准直透镜14发射激光，激光经第一准直透镜14准直后传输至第一斜面镜12，所述第一斜面镜12全发射激光至第二斜面镜13，所述第二斜面镜13折射部分激光并水平传输到第一聚焦透镜16，激光经第一聚焦透镜16聚焦后传输至光纤40；所述第二斜面镜13反射部分激光到第二聚焦透镜15，激光经第二聚焦透镜15聚焦后传输至监测组件30，所述监测组件30接收反射激光并监测反射激光的功率参数。
其中，所述接收组件的光路传输如下述：激光通过光纤40射向第二准直透镜23，激光经第二准直透镜23准直后传输至第三斜面镜21，所述第三斜面镜21对激光进行全反射的同时并进行聚焦，避免激光溢出通光孔径，随着光路传输，传输至第三聚焦透镜24，激光经第三聚焦透镜24聚焦后射向第三准直透镜25，再经过第三准直透镜25准直后传输至接收芯片22，所述接收芯片22接收激光。
在本实施例中，所述第一斜面镜12与射向其表面的激光呈150°，所述第二斜面镜13与射向其表面的激光呈150°，所述第三斜面镜21与射向其表面的激光呈135°。当然，所述第一斜面镜12、第二斜面镜13和第三斜面镜21的倾斜角度主要取决于分光后激光的夹角，并不唯一。
优选地，所述SR4器件整体为一体成型。
如图4所示，本发明还提供一种监测方法的较佳实施例。
本发明还提供一种监测方法，所述监测方法用于如上所述的SR4器件，所述监测方法包括以下步骤：
步骤10、所述发射芯片发出激光至第一斜面镜；
步骤20、所述第一斜面镜全发射激光至第二斜面镜；
步骤30、所述第二斜面镜折射部分激光到光纤，并反射部分激光到监测组件；
步骤41、激光通过光纤射向第三斜面镜；
步骤42、所述监测组件接收反射激光并监测反射激光的功率参数；
步骤411、所述第三斜面镜将激光全反射并聚焦到接收芯片；
步骤412、所述接收芯片接收激光。
综上所述，以上仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内所做的任何修改，等同替换，改进等，均应包含在本发明的保护范围内。
