研制了一种在光纤中制造反射型陷波耦合器的方法。该耦合器由一个45°微棱镜组成，该微棱镜穿透多模光纤的芯。与光纤轴成90°的一个面为非反射面，与光纤轴成45°的一个面为反射面。我们制造凹口并选择性地仅镜像45°面的方法成本低、精度高且易于扩展。耦合器允许光从侧面接近100%地耦合到光纤中，同时允许光的任何期望部分在光纤的相对侧上以90°角从芯耦合出来。
A method of fabricating a reflective notch coupler in an optical fiber has been developed. The coupler consists of a 45° microprism that penetrates into the core of a multimode optical fiber. One face, at 90° to the fiber axis, is nonreflective, and one face, at 45° to the fiber axis, is reflective. Our method of fabricating a notch and selectively mirroring only the 45° face is low-cost, precise, and easily scalable. The coupler allows near-100% coupling of light into an optical fiber from the side, while allowing coupling of any desired fraction of light out from the core at a 90° angle on the opposite side of the fiber.
