摘要	A device for coupling incident radiation to a single mode fiber optic a solid state interferormeter having a front end similar to a Mach-Zehnder integrated interferometer and a back end formed by two converging radiation channels converging at an angle theta and terminating prior to overlapping. The angle theta is calculated to produce an interference zone formed by the exiting radiation a primary constructive interference fringe that provides an optimum match to an input fiber mode of a fiber positioned within the interference zone.
其他摘要	一种用于将入射辐射耦合到单模光纤的装置，一种固态干涉仪，其具有类似于Mach-Zehnder集成干涉仪的前端和由两个会聚辐射通道形成的后端，所述两个会聚辐射通道以角度θ会聚并在重叠之前终止。计算角度θ以产生由出射辐射形成的干涉区，主要构造干涉条纹提供与位于干涉区内的光纤的输入光纤模式的最佳匹配。
主权项	An integral solid state radiation coupler comprising a radiation input end and a radiation output end said radiation input end connected to said radiation output end through two diverging and two converging radiation paths wherein said radiation path converge to said output end at an angle 2.theta. wherein .theta. is an interference angle calculated to produce an exiting radiation interference pattern of radiation entering said input end at an interference zone outside said output end, wherein said radiation entering said input end has an energy and said interference pattern has a primary constructive interference fringe adapted to maximize energy transfer efficiency between said entering beam and a radiation receiver input end positioned in said interference zone by matching said primary constructive interference fringe mode to said radiation receiver input end mode.
