- OPTICAL FIBER PUMP-SIGNAL COMBINER AND METHOD OF MANUFACTURING FOR PUMP-SIGNAL COMBINER

摘要

The present invention is characterized in that a rod optical fiber and a clad optical fiber are included in an inner space of a cylindrical tube and are thermally deformed to taper from one end to the other end and the space between the rod optical fiber and the plurality of clad optical fibers at the other end is limited Structure fiber optic pump-signal coupler. By using the thermal deformation of the rod optical fiber and the clad optical fiber, it is possible to manufacture a device that simultaneously guides the signal and the pump by a simpler method. Therefore, the fabrication cost of the device can be reduced and the fabrication efficiency can be improved.
