Abstract
Example devices are optical dividers including: a first optical coupler; a second optical coupler; and a third optical coupler. The devices also comprise a first optical fiber integrated in the first optical coupler, the first optical fiber coupled to an optical combiner, and a second optical fiber integrated in the first optical coupler and in the second optical coupler, the second optical fiber coupled to the optical combiner. The devices further comprise a third optical fiber integrated in the second optical coupler and in the third optical coupler, the third optical fiber coupled to the optical combiner. The optical combiner includes: a first output coupler; a second output coupler; and the optical combiner couples a subset of the first through third optical fibers to the first output coupler; and the optical combiner couples a subset of the first through third optical fibers to the second output coupler.
