Abstract: In an example, a system comprises a first optical device, a second optical device, and an optical modulator. The first optical device, in a non-cryogenic environment, receives a light signal, outputs the light signal, receives a first modulated light signal, and outputs the first modulated light signal into the non-cryogenic environment. The second optical device, in a cryogenic environment, receives the light signal from the first optical device, outputs the light signal, receives the first modulated light signal, and outputs the first modulated light signal. The optical modulator, in the cryogenic environment, receives the light signal from the second optical device, modulates the light signal to produce the first modulated light signal and a second modulated light signal, outputs the second modulated light signal, and outputs the first modulated light signal to the second optical device.

Abstract: 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.
