摘要: 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.

摘要: Optical-fiber connector modules are disclosed. In one example, an optical-fiber connector module can include a receptacle, a cable, and an optical fiber within at least the cable. The receptacle can be configured to accept insertion of a first plug for establishing a first optical connection between the optical-fiber connector module and an optical-fiber stylet of a medical device. The cable can include a second plug for establishing a second optical connection between the optical-fiber connector module and an optical interrogator. The optical fiber can extend from the receptacle through the cable to the second plug. The optical fiber can be configured to convey input optical signals from the optical interrogator to the optical-fiber stylet and reflected optical signals from the optical-fiber stylet to the optical interrogator.

摘要: A single-core polarization-maintaining dispersion compensation micro-structured optical fiber comprises a fiber core, a first layer of air holes surrounding the fiber core, the cladding defects on the x-axis, the cladding defects on the y-axis, and the cladding. The air holes in the fiber cross section are arranged in the equilateral triangle lattice. Three consecutive air holes are omitted to form a solid area. This solid area is the fiber core. There are two cladding defects along the x-axis. Their centers are respectively located at the two vertices of the hexagon on the x-axis, which is formed by the fourth air hole ring from the core exclusive the central air hole. Each cladding defect along the x-axis contains 7 air holes and goes through from the core by only 1 layer of air holes. There are also two cladding defects along the y-axis.
