摘要	An optical communication signal source package and assembly for coupling optical signals to the end of an optical fiber includes first and second semiconductor laser diodes capable of being operated in a redundant fashion for increased reliability or to provide wavelength division multiplexing for increases in bandwidth and information carrying capability. The laser diodes are supported with their mounting flanges in a common plane and are oriented to provide parallel beams of polarized light having perpendicular E-field vectors. A connector carried by the support positions the optical fiber at the target area where an optics system focuses the light beams. An optical coupling device such as a polarizing beam splitter or a holographic beam separator is responsive to the orthogonal light beams to direct both light beams toward the optical fiber with minimum decrease in amplitude. The package includes no moving parts or highly frequency selective components. The package is employed in a compact communication signal coupling assembly permitting short electrical lead lengths and high circuit density.
其他摘要	用于将光信号耦合到光纤末端的光通信信号源封装和组件包括第一和第二半导体激光二极管，其能够以冗余方式操作以提高可靠性或提供波分复用以增加带宽和信息携带能力。激光二极管的安装凸缘支撑在一个共同的平面上，并且定向成提供具有垂直E场矢量的平行偏振光束。由支撑件承载的连接器将光纤定位在光学系统聚焦光束的目标区域处。诸如偏振分束器或全息光束分离器的光学耦合装置响应于正交光束以将两个光束引向光纤，同时振幅的减小最小。该封装不包括移动部件或高频选择性部件。该封装用于紧凑的通信信号耦合组件，允许短的电引线长度和高电路密度。
