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.
Claims20
A method for forming a side-pumped optical fiber combiner,
- the method comprising:
- ablating a cladding of a signal fiber to form an angled notch in the cladding, the signal fiber comprising a core and the cladding surrounding the core;
- inserting a cladding-free end of a pump fiber into the angled notch, the pump fiber comprising a core and a cladding, the cladding-free end comprising an end and a longitudinal portion of the core of the pump fiber free from the cladding of the pump fiber;
- and
- fusing the cladding-free end to the signal fiber.
A method for forming a side-pumped optical fiber combiner,
- the method comprising:
- generating a laser beam such that the laser beam impacts and ablates a cladding of a signal fiber to form an angled notch in the cladding, the signal fiber comprising a core and the cladding surrounding the core, wherein the angled notch extends only into the cladding of the signal fiber and does not extend into the core of the signal fiber, and wherein the angled notch is longitudinally aligned with a longitudinal axis of the signal fiber;
- inserting a cladding-free end of a pump fiber into the angled notch, the pump fiber comprising a core and a cladding, the cladding-free end comprising an end and a longitudinal portion of the core of the pump fiber free from the cladding of the pump fiber;
- and
- fusing the cladding-free end to the signal fiber.
