ABSTRACT:
A mode scrambler is interconnected between a light source and an optical fiber coupler made of a plurality of graded index multi-mode optical fibers. The mode of the input light signals can be converted to a random pattern mode through the mode scrambler, so that a steady excitation state of the input light can be realized, including not only dominant lower modes but also higher modes of the input light signals, resulting in enabling to divide the input light signals without any irregularity of the output light power.
