摘要	1466486 Light guide termination with source and detector CORNING GLASS WORKS 3 Jan 1975 [7 Jan 1974] 179/75 Heading G1A Such a termination, arranged to be positioned in axial alignment with the end of waveguide bundle 10, comprises optical mixer 18 with face 16 adjacent said end and a solid state detector 34 near a second face 20 edge-emitting solid state light source 32 on the side of detector 34 away from mixer 18 and reflecting surface 48 so disposed as to reflect light from source 32 to face 20. Ferrule 12 of say brass or glass maintains the ends of waveguides 11 in parallel alignment and has similar grinding characteristics to them, Rod 18 is preferably cylindrical with its ends perpendicular to its axis and clad with layer 22 of lower refractive index. Support member 24 is secured to ferrule 12 by means 26. Contact 36 supported by housing 38 serves as heat sink for double heterojunction LOC laser diode 32 operating below the lasing threshold as an incoherent emitter. Flying lead 40 is the other connection. Electrical connection to p-i-n or avalanche photo- diode 34 is by beam lead 42 and flying lead 44. All leads are insulated. Parabolic surface 48 which collimates the light from source 32 is formed by depositing silver, or chromium, or surface 46 is polished. Detector 34 is held by adhesive filling 54 of silicon fluid or ethyl-cyanacrylate epoxy or methyl siloxane. In the embodiment of Fig. 2 (not shown), the surface of adhesive filling is flat and contacts the second end face of rod (18'), the reflecting surface is conical and the detector is mounted on an insulating layer on source 32. The adhesive filling may be omitted and the mixer rod end disposed on the detector.
其他摘要	1466486带光源和探测器的光导终端CORNING GLASS WORKS 1975年1月3日[1974年1月7日] 179/75标题G1A这种终端设置成与波导束10的末端轴向对齐，包括带有面16的光学混频器18邻近所述端部和固态探测器34靠近第二面20，边缘发射固态光源32位于探测器34的远离混合器18和反射表面48的一侧，以便将来自光源32的光反射到面20上。如图12所示，黄铜或玻璃保持波导11的端部平行排列并具有与它们类似的研磨特性，杆18最好是圆柱形的，其端部垂直于其轴线并包覆有较低折射率的层22。支撑构件24通过装置26固定到套圈12上外壳38用作双异质结LOC激光二极管32的散热器，其作为非相干发射器在激光阈值以下工作。飞线40是另一个连接。与p-i-n或雪崩光电二极管34的电连接是通过光束引线42和悬空引线44.所有引线都是绝缘的。通过沉积银或铬形成准直来自光源32的光的抛物面48，或抛光表面46。检测器34由硅流体或乙基丙烯酸乙酯环氧树脂或甲基硅氧烷的粘合剂填充物54保持。在图2的实施例（未示出）中，粘合剂填充表面是平的并且接触杆（18'）的第二端面，反射表面是圆锥形的并且检测器安装在源32上的绝缘层上。可以省略粘合剂填充物并且将混合器杆端部设置在粘合剂填充物上探测器。
