Claim 0:
1. An optical combiner comprising:
a plurality of first input optical fibers that each include a core;
a bridge fiber that includes:
a bridge input surface including a single core, the single core being optically connected to all of the cores of the plurality of first input optical fibers;
a diameter reduction portion having a diameter that decreases away from the bridge input surface along an optical axis of the optical combiner; and
a bridge output surface located opposite to the bridge input surface along the optical axis;

an intermediate optical fiber that includes a core connected to the bridge output surface of the bridge fiber;
a second input optical fiber that includes a core; and
an output optical fiber that includes:
a first optical waveguide connected to the core of the intermediate optical fiber; and
a second optical waveguide connected to the core of the second input optical fiber.
