| 1. A fiber-based light source device, comprising:
a plurality of first light-emitting devices for emitting a plurality of first lights;
a plurality of second light-emitting devices for emitting a plurality of second lights;
a plurality of third light-emitting devices for emitting a plurality of third lights;
a plurality of first directional couplers for coupling the first lights in their order so as to generate a first coupled light;
a plurality of second directional couplers for coupling the second lights in their order so as to generate a second coupled
light;
a plurality of third directional couplers for coupling the third lights in their order so as to generate a third coupled light;
a fourth directional coupler for coupling the first coupled light and the second coupled light so as to generate a fourth
coupled light; and
a fifth directional coupler for coupling the third coupled light and the fourth coupled light so as to generate an output
light source.
