摘要	A coupling technique for the side coupling of light from a light source into a waveguide is provided, A transversal groove is made into a section of the waveguide, extending into the target light guiding region. A coupling element is coupled to the light source at one of its end to receive the light beam therefrom. The opposite end of the coupling element is inserted in the groove and has at least one reflecting interface which specularly reflects the light beam for propagation into the waveguide. This technique may advantageously be used to couple light from the laser diodes of an array into one or a plurality of optical fibers.
其他摘要	提供了用于将光从光源侧向耦合到波导中的耦合技术。横向沟槽被制成波导的一部分，延伸到目标光导区域中。耦合元件在其一端耦合到光源以从其接收光束。耦合元件的相对端插入凹槽中并具有至少一个反射界面，该反射界面镜面反射光束以传播到波导中。该技术可有利地用于将来自阵列的激光二极管的光耦合到一个或多个光纤中。
主权项	An optical coupling device for coupling light emitted by an array of laser diodes into at least one waveguide, the device comprising: a substrate; a plurality of waveguide sections of said at least one optical waveguide affixed to the substrate in a parallel relationship with each other, each of said waveguide sections having a light propagating layer extending along a longitudinal axis and a groove extending therein transversally to said longitudinal axis, said groove reaching into the light propagating layer; and a coupling element far coupling light from a plurality of laser diodes of said array into said waveguide sections, the coupling element having a first end optically coupled to the plurality of laser diodes for receiving the light therefrom, and a second end extending in the groove of each of said plurality of waveguide sections and having at least one reflection interface oriented to reflect said light to propagate into the light propagating layer of the corresponding waveguide section.
