| 英文摘要 | Systems and methods are described for the construction of micro-optical couplers incorporating optical tapers to reshape multimode optical inputs. Incorporating tapers allows the spatial properties of the multimode inputs to be adjusted to match to the spatial properties of the output fiber, even in systems that are limited to unity-magnification imaging optics. In an exemplary embodiment, a larger-core multimode fiber and a smaller-core double-clad fiber are glued into a glass capillary, with the multimode fiber tapering to a smaller diameter inside the capillary. Polishing the capillary to expose the taper gives a multimode core that is smaller than the double-clad core. Imaging with unity magnification through a GRIN lenses and a dichroic reflector transfers the multimode input efficiently to the double-clad fiber with greater efficiency than would have been possible with the same optics and an untapered fiber. The dichroic reflector is transparent to a second singlemode signal input, which is collimated by a second GRIN lens and coupled to through the reflector to the core of the double-clad fiber. An isolator may be included in the signal beam path, and the double-clad fiber may be replaced by a double-clad gain fiber. |
