摘要	An optical communications module is provided with an optical coupling system that includes a reflective and focusing (RAF) lens and an index-matching material that together allow air gaps along the optical pathway, which are typically associated with the use of refractive optical elements used in known optical communications modules, to be eliminated. Eliminating these air gaps allows Fresnel reflection along the optical pathway to be eliminated, or at least greatly reduced. Eliminating or reducing Fresnel reflection reduces insertion loss and optical crosstalk in the optical communications module.
其他摘要	光学通信模块设置有光学耦合系统，该光学耦合系统包括反射和聚焦（RAF）透镜和折射率匹配材料，它们一起允许沿光学路径的气隙，这通常与使用的折射光学元件相关联。已知的光通信模块，将被淘汰。消除这些气隙允许消除或至少大大减少沿光学路径的菲涅耳反射。消除或减少菲涅耳反射减少了光通信模块中的插入损耗和光学串扰。
主权项	An optical transmitter (Tx) module comprising: an optical Tx portion, the optical Tx portion including at least a first light source for producing a first light beam and a first collimating lens for collimating the first light beam to produce a first collimated light beam; an optical coupling system, the optical coupling system being positioned to receive a first collimated light beam corresponding to at least a portion of the first collimated light beam produced in the optical Tx portion, the optical coupling system having at least a first optical port having a first end of at least a first optical fiber mechanically coupled thereto, and wherein the optical coupling system includes at least a first reflective and focusing (RAF) lens that reflects the received first collimated light beam along a first optical pathway of the optical coupling system toward the first optical port and focuses the received collimated light beam on the first end of the first optical fiber, the first optical pathway extending from the first RAF lens to the first optical port, and wherein the optical coupling system is formed in a piece of material that is transparent to a wavelength of the first light beam produced by the first light source and that is devoid of air gaps at least along the first optical pathway; and a refractive index-matching material disposed in between, and in contact with, the first optical port and the first end of the first optical fiber such that no air gaps exist in between the first optical port and the first end of the first optical fiber.
