Abstract
A terminated hollow-core optical fiber includes a capillary, a hollow-core optical fiber including a structured cladding, and an endcap. A first end of the hollow-core optical fiber terminates inside the capillary a non-zero distance away from a first end face of the capillary. The hollow-core optical fiber is adhered to the capillary at a second end face of the capillary where the hollow-core optical fiber extends out of the capillary. The endcap is fused to the first end face of the capillary. The endcap has a larger diameter than the first end of the hollow-core optical fiber. This termination scheme does not require fusing the hollow-core fiber itself to the endcap or any other part. Therefore, this termination scheme is applicable to hollow-core fibers with a structured cladding that cannot tolerate the temperatures associated with fusing the hollow-core fiber to another part.
