摘要： A tapered waveguide optical mode transformer (20) includes a tapered core formed on a planar substrate structure (16). To vertically taper the core (21), steps (22) are etched into the top surface of the core. The steps have depths and lengths along the optical axis of tapered waveguide that are selected to transform the optical mode characteristics of a desired optical fiber to the optical mode characteristics of a desired planar waveguide. The core can also be tapered horizontally to form a 2-D tapered waveguide. The tapered waveguide can be integrally included in planar lightwave circuits (PLCs) to reduce light coupling losses between optical fibers and the PLC waveguides.

摘要： A connector (100) for a plurality of optic fibers (106-107) includes a polymer layer deposited over the ends of the fibers at the face of the connector (100) to reduce insertion loss. The polymer layer (110) may be a single layer which encompasses all of the ends of the plurality of fibers (106-107), or separate layers deposited at each of the ends of the plurality of fibers. These layers may be configured to be generally square, rectangular, circular or elliptical. Additional layers of the polymer may be deposited on the face between alignment hole and the housing.

摘要： Two techniques are disclosed for writing waveguides between laser diodes and an optical fiber such that the laser diodes are aligned with their respective waveguide facets. The first technique utilizes a light sensitive polymer, such as a ultra-violet (UV) cross-linkable polymer. A precision writing system locates the light emitting centers of the laser diodes and writes the waveguide circuit by exposing the waveguiding regions with the appropriate light. The unexposed areas of the core layer are developed with a solvent and removed. The entire device is then encapsulated with a low-index cladding polymer. The second technique utilizes an active polymer approach in which waveguide regions are formed when the writing beam aligns the dipole molecules in the polymer to cause a change in the refractive index of the polymer.
摘要翻译：公开了用于在激光二极管和光纤之间编写波导的两种技术，使得激光二极管与它们各自的波导面成对准。第一种技术使用光敏聚合物，例如紫外（UV）可交联聚合物。精密写入系统定位激光二极管的发光中心，并通过用合适的光使波导区域曝光来写入波导电路。核心层的未曝光区域用溶剂显影并除去。然后将整个装置用低折射率包层聚合物包封。第二种技术利用活性聚合物方法，其中当写入光束将聚合物中的偶极子分子对准以引起聚合物的折射率变化时，其中形成波导区域。

摘要： Fiber optic connections are accomplished with passive alignment using a modular approach. An improved waveguide substrate has precisely aligned waveguides secured in place, including at an inlet channel, an outlet channel, or both. The waveguides need not extend beyond the face of the inlet or outlet location, and there is no need to have any unsupported fiber optic fibers connect to the waveguide substrate. When provided, a connector module or modules have fiber optic fibers having supported ends which precisely align with the waveguides of the waveguide substrate. Connecting pins typically are provided to insure alignment between waveguides and fibers is easily attained.
