First Claim
Patent Images
1. A fiber optic tap, comprising:
- at least one pair of first and second fibers, said fibers adapted to carry a signal;
an interface between said first and second fibers configured to direct a portion of the signal out of said fibers; and
a photodetector for detecting the portion of the signal directed out of said fibers.

Abstract
A fiber tap with configurable wavelength and polarization sensitivities and which may include a fiber connector is described. In one embodiment, light reflected from an interface between a pair of fibers is reflected into a photodetector with the option of an intermediate light pipe. In another embodiment, light reflected from an interface between a pair of fiber sections is reflected into an etched opening. The opening is filled with an index matching material and includes a mirrored surface. The reflected light is directed from the mirrored surface to a photodetector. In each embodiment, an assembly technique for tapping arrays of several fibers is supported.

14. A method for making a fiber optic array, comprising:
-
positioning at least one fiber in a first substrate, wherein the fiber is adapted to carry a signal;
cutting the fiber into a first fiber section and a second fiber section;
configuring an interface between the first and second fiber sections to enable a portion of the signal to be directed out of the fiber sections; and
providing a photodetector at a location where it can receive the portion of the signal to be directed out of the fiber sections. - View Dependent Claims (15, 16, 17, 18, 19, 20)
