Abstract
A method for forming a side-pumped optical fiber combiner includes ablating a cladding of a signal fiber to form an angled notch in the cladding. The signal fiber includes a core and the cladding surrounding the core. The method further includes inserting a cladding-free end of a pump fiber into the angled notch. The pump fiber includes a core and a cladding, the cladding-free end including the core of the pump fiber and free from the cladding of the pump fiber. The method further includes fusing the cladding-free end to the signal fiber.
