-1- Abstract A mode scrambler is connected between a light source and an optical fiber coupler formed 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 of the input light can be realized, including not only dominant lower modes but also higher modes of the input light signals, resulting in division of the input light signals without irregularity of the output light power. This arrangement enables a semiconductor laser to be used as the light source without disadvantage, while taking advantage of the higher power of the semiconductor laser.
