摘要	An optical two-way transmission-receiver communications system utilizing a coaxial coupler in place of a standard coupler, the optical system being capable of operation either in a single or multiple wavelength mode by designing the coupling region to have the proper length (i.e., either in 3dB or WDM operation), and further comprising a transmitter and a detector adjacent a coaxial coupler. The detector of the system is provided with a hole in its center in order to allow the transmitter access to the core waveguide of the coaxial coupler. The coaxial coupler may be formed from a rod in tube structure with a core waveguide extension adjacent the Tx/Rx and an integral pigtail on the opposite side of the coupler.
其他摘要	一种光学双向发送 - 接收器通信系统，利用同轴耦合器代替标准耦合器，该光学系统能够通过设计耦合区域以具有适当的长度而以单波长或多波长模式操作（即，在3dB或WDM操作中，还包括与同轴耦合器相邻的发射器和检测器。系统的探测器在其中心设有一个孔，以便允许发射器接入同轴耦合器的核心波导。同轴耦合器可以由管状结构形成，其中芯波导延伸部分与Tx / Rx相邻，并且在耦合器的相对侧具有整体尾纤。
主权项	Coaxial optical coupler having a core waveguide inside a ring waveguide, comprising: a tube, at least a portion of which comprises a glass having a refractive index less than that of a raised refractive index part of said core waveguide; and, a core member, at least a portion of which is disposed inside said tube, said core member comprising at least the raised refractive index part of said core waveguide; said tube and said core member being integrally formed from a rod structure and a tube structure that are fused together by heating.
