摘要	An accurate and inexpensive integral micro-optical system for coupling and aligning optical fibers with other optical components, such as other optical fibers, diffusers, beam shapers, beam splitters, mirrors, or lenses is disclosed. The micro-optical coupler disclosed comprises one or more fiberport collimators and one or more microlens arrays, optically aligned during fabrication so that an optical fiber, or other source of light, was coupled to another optical fiber, or other light receiver, by simple inserting the optical source in one side of the micro-coupler and inserting the optical receiver in the other side of the micro-coupler. Often the fabrication process for this system can be done in a single lithography procedure. Since the optical axis of each component was aligned during the fabrication step, no subsequent alignment was required.
其他摘要	本发明公开了一种精确且廉价的整体微光学系统，用于将光纤与其他光学元件耦合和对准，例如其他光纤，漫射器，光束整形器，分束器，镜子或透镜。所公开的微光耦合器包括一个或多个光纤端口准直器和一个或多个微透镜阵列，在制造期间光学对准，使得光纤或其他光源通过简单插入耦合到另一光纤或其他光接收器。微耦合器一侧的光源，将光接收器插入微耦合器的另一侧。通常，该系统的制造过程可以在单个光刻过程中完成。由于在制造步骤期间对准每个部件的光轴，因此不需要后续对准。
主权项	An integral device that is adapted to optically couple a plurality of optical fibers to a plurality of optical elements; wherein said device comprises: (a) a substrate; (b) a first collimator array, rigidly attached to said substrate, wherein said first collimator array comprises a plurality of first through-holes, wherein each of said first through-holes is adapted to receive an optical fiber and to hold the optical fiber in position, and wherein each of said first through-holes has a fixed position relative to said substrate; (c) a second collimator array, rigidly attached to said substrate, wherein said second collimator array comprises a plurality of second through-holes, wherein each of said second through-holes is adapted to receive an optical element and to hold the optical element in position, and wherein each of said second through-holes has a fixed position relative to said substrate; and (d) one or more lens arrays, rigidly attached to said substrate, wherein each said lens array comprises a plurality of optical lenses, wherein the optical properties and positions of each of said lenses are adapted to optically couple an optical fiber positioned in one of said first through-holes to an optical element in one of said second through-holes, and wherein each of said lenses has a fixed position relative to said substrate; and wherein: (e) said device, including said substrate, said first and second collimator arrays, and said one or more lens arrays, is integral, formed from a single, polymeric piece.
