Abstract
A method for providing an electric waveform at a cryogenic temperatures includes providing an optical signal, which comprises an optical waveform, guiding the optical signal into a cryogenic chamber, and converting the optical waveform of the optical signal into an electric waveform inside the cryogenic chamber.
Claims15
A method for providing an electric waveform, the method comprising:
- providing a first optical signal, which comprises one or more sequences of optical pulses,
- guiding the first optical signal into a cryogenic chamber,
- distributing the optical pulses of the first optical signal via optical waveguides to two or more optical-to-electrical converter devices, and
- converting the optical pulses of the first optical signal into electric pulses inside the cryogenic chamber by using the optical-to-electrical converter devices,
- wherein an internal temperature inside the cryogenic chamber is lower than 20 Kelvin.

An apparatus, comprising:
- an optical pattern generator device to provide a first optical signal, which comprises one or more sequences of optical pulses,
- a cryogenic chamber,
- a cooling system arranged to keep an internal temperature of the cryogenic chamber lower than 20 Kelvin,
- an optical feedthrough to guide the first optical signal into the cryogenic chamber,
- one or more distributors to distribute the optical pulses of the first optical signal via optical waveguides to two or more optical-to-electrical converter devices, and
- one or more optical-to electrical converter units to convert the optical pulses of the first optical signal into electric pulses inside the cryogenic chamber.
