摘要	An optical fiber side coupler apparatus comprising a first optical fiber and at least one multimode (MM) optical fiber having a core, the MM optical fiber for delivering light to the first optical fiber. The MM optical fiber can comprise a first length having a first location therealong wherein the core comprises a first cross sectional area A1, a second length having a second location therealong wherein the core comprises a second cross sectional area A2 that is less than the first cross sectional area A1, and a transition section, located between the first and second locations, wherein the cross sectional area of the core of the MM optical fiber is reduced. The second length can be secured alongside a selected length of the first optical fiber so as to provide optical coupling between the MM optical fiber and the first optical fiber. The MM optical fiber can be free of any progressively tapered length secured with the first optical fiber in a manner that would provide substantial optical coupling between the MM optical fiber and the first optical fiber.
其他摘要	一种光纤侧耦合器装置，包括第一光纤和至少一个具有芯的多模（MM）光纤，该MM光纤用于将光传送到第一光纤。 MM光纤可包括具有沿其的第一位置的第一长度，其中芯包括第一横截面区域A1，第二长度具有沿其的第二位置，其中芯包括小于第一横截面的第二横截面区域A2。截面积A1和位于第一和第二位置之间的过渡部分，其中MM光纤的纤芯的横截面积减小。第二长度可以与第一光纤的选定长度一起固定，以便在MM光纤和第一光纤之间提供光学耦合。 MM光纤可以没有以第一光纤固定的任何渐进锥形长度，其方式是在MM光纤和第一光纤之间提供实质上的光学耦合。
