Abstract
An optical coupling module, including a transmission optical fiber and at least one pump optical fiber, is provided. The transmission optical fiber has a central shaft extending along a longitudinal direction and includes a first transmission flat portion, a second transmission flat portion, and a transmission tapered portion. The transmission tapered portion is connected between the first transmission flat portion and the second transmission flat portion. The at least one pump optical fiber extends along the longitudinal direction and includes a pump flat portion and a pump tapered portion. The pump flat portion is disposed on the first transmission flat portion. The pump tapered portion is connected to the pump flat portion. A distance from an outer surface of the pump tapered portion to the central shaft gradually decreases from adjacent to the pump flat portion toward a direction away from the pump flat portion.
