Abstract: A radial power feedback sensor senses the power output of a fiber optic bundle. The fiber optic bundle is arranged generally radially about an axis to carry radiative energy produced by a laser. A spacer is positioned within the fiber optic bundle such that the fiber optic bundle generally surrounds the spacer. The spacer serves to enable the radiative energy to pass therethrough. A photo detector is then disposed adjacent the spacer and is operable to output a signal in response to a measured intensity of the radiative energy passing through the spacer. Accordingly, due to the surrounding of the fiber optic bundle around the photo detector, a greater number of individual photo optic lines are exposed to the photo detector, thereby decreasing the variance between the measure output and the true output of the laser.

Abstract: In an all optical switch an imaging system is interposed between the micro lens array and the moveable micro mirrors of a MEMS device to which, or from which, the light beams are directed. This causes an image of the micro lens array to be formed at the MEMS device, or vice-versa, thus effectively eliminating the distance between the micro lens array and the MEMS device. The imaging system may be a telecentric system. The size of the arrangement may be reduced by compacting the optical path, e.g., using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirror. The overall system is arranged to account for any inversions introduced.

This can be achieved in a variety ways. This may be achieved a) when each fiber is associated with a respective micro lens of a micro lens array, by insuring that there is a different distance between the centers of adjacent micro lenses than there is for the centers of their corresponding adjacent fibers, b) when the fibers are terminated by collimators, the direction of the collimators is adjusted to point the beams in a converging manner and c) by employing an optical system that changes the direction of various ones of the beams may be interposed between a) the fiber bundle and b) the corresponding MEMS device.

Abstract: A system and method for the vacuum assisted insertion of optical fibers includes a plate with one or more fiber alignment holes and a vacuum-sealed region on the exit end of the alignment holes. A vacuum source is connected to the vacuum-sealed region and creates a partial vacuum which draws air through the alignment holes creating an airstream into the alignment hole. As a fiber is moved toward the alignment hole, the airstream converging on the hole creates a centering force which acts to pull the fiber into alignment with the hole and the fiber passes directly into the hole. The use of a vacuum produces a precise alignment of a fiber or fibers that can be automated and is significantly quicker and more efficient than any other existing apparatus.

A VCSEL or detector to optical fiber plug assembly is thus provided.

Abstract: The present invention provides an optical interconnection device whereby arrays of fibers or waveguides arranged in a given orientation at an input side are rearranged within the device and exit at an output side arranged in a different orientation from the input side. The method of accomplishing the rearrangement is to first arrange a plurality of ribbon fibers each containing a plurality of individual fibers.

As a result of the slicing, distinct arrays are created at the output side. Alternatively, distinct arrays are created at the output side via manual or automated placement based on a roadmap.

Abstract: Improved techniques for manipulation and management of fiber optic light. An improved fiber optic probe assembly for low light spectrographic analysis improves response to subtle light-matter interactions of high analytical importance and reduces sensitivity to otherwise dominant effects. This is accomplished by adjusting the illumination and collection fields of view in order to optimize the probe's sensitivity. Light manipulation is applied internal to the fiber so that the probe's delivery pattern and field of view do not require external manipulation and are not adversely affected by investigated media. This allows the light delivery pattern or field of view or both to be aggressively steered off-axis to achieve significant increased performance levels. Aggressive beam steering is accomplished by employing internally reflective surfaces in the fiber. A reflective metal coating or low refractive index coatings or encapsulants can be used to ensure total internal reflection.
