US Patent 9880365 Fiber-optic feedthroughs for superconducting systems

Interconnect systems for coupling a first system operating in a first type of environment (e.g., a cryogenic environment) to a second system operating in a second type of environment (e.g., a non-cryogenic environment) are provided. An interconnect system includes a first connector coupled to optical fibers that are coupled to the first system operating in the first type of environment. The interconnect system further includes a second connector coupled to optical fibers that are coupled to the second system operating in the second type of environment. The interconnect system may include an optical window configured to couple optical signals between the optical fibers, and the optical window is configured to maintain a vacuum seal between the first type of environment and the second type of environment such that the first type of environment is substantially thermally isolated from the second type of environment.
