An optical assembly has a miniature fiber optic bend fixedly attached to a substrate to form an integral assembly with an optical component also fixedly attached to the substrate. The assembly includes at least one optical fiber having an entering fiber portion and a return fiber portion. A miniature bend is formed in an intermediate portion that comprises an optical fiber portion between the entering fiber portion and the return fiber portion to provide a reversal of direction between the entering fiber portion and the return fiber portion. The entering fiber portion and the return fiber portion are preferably fixed in overlying relationship within a channel formed in the substrate. The resulting device is smaller, more environmentally stable, and more robust, because there is no relative motion between components. The resulting device also has fewer parts and processing steps to manufacture.

Single-sided fiber optic splitter with integral miniature bend

A fiber optic device for changing direction along a fiber optic path is provided using an asymmetrical miniature bend. The fiber optic device with the miniature bend is particularly suitable for components in which one of the fiber portions lies close to a surface, such as a single sided splitter. A method of forming such an asymmetrical miniature bend in optical fibers is also provided. In one embodiment to form the asymmetrical bend, entering and exiting fiber portions are offset along parallel axes prior to bending an intermediate portion. In another embodiment, the intermediate portion is heated at a location that is offset from a bending axis.
