Abstract
A fiber optic power coupling device such as a power summer, power divider or star coupler comprises a segment of multimode optical fiber having an input mirror at one end and an output mirror at the opposite end. One or more inputs at the input end of the fiber segment direct an equivalent number of input, intensity modulated light signals into the fiber and one or more outputs at the output end direct a corresponding number of output signals out of the fiber. Where there is one input and a plurality of outputs, the device acts as a power divider. Where there are a plurality of inputs and one output, the device acts as a power summer. Where there are a plurality of inputs and a plurality of outputs, the device acts as a star coupler.
