AB  - This paper presents the results of a performanceevaluation of a photonic link in a cryogenic environment. Thetransmission from room temperature to 4.7K was achievedusing a 904nm and 1310nm lasers with a bandwidth exceeding1 GHz using both silicon-based and InGaAs-based commercialphotodiodes. A reduction in DC photocurrent was observed.Moreover, the frequency response measurements demonstratethat both photodiodes improve their maximum bandwidth evenwhen unbiased at cryogenic environment. Furthermore, thiswork presents a demonstration of photonic control of cryogenicelectronics for quantum computing applications.
