    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: A light receiving module is provided, including a beam contraction module, a multi-core multi-mode waveguide, and a detector. The beam contraction module is configured to receive a first optical signal, and contract a mode spot of the first optical signal, to obtain a second optical signal. The multi-core multi-mode waveguide includes a cladding layer and N waveguides. The multi-core multi-mode waveguide is configured to: receive the second optical signal, and concentrate energy of the second optical signal in a plurality of waveguides of the N waveguides, to obtain a plurality of third optical signals. A plurality of sub-detectors are in one-to-one correspondence with the plurality of third optical signals. The plurality of sub-detectors are configured to receive the plurality of third optical signals, to obtain a plurality of electrical signals based on the plurality of third optical signals.

    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.
