Tenders Are Invited For Integrated Cryogenic Optical Readout

Tenders are invited for T512-901GS Integrated Cryogenic Optical Readout for Scalable Single-Photon Detectors Arrays (EXPRO+) Tender Action Number: 1-13338 Activity Number: 1000045842 Clarification Request Deadline 01/06/2026 13:00 CET Closing Date Extension Request Deadline 01/06/2026 13:00 CET Announcement Date 05/03/2026 Last Update On 30/04/2026 12:59 CET Update Reason Tender Action Issued The increasing demand for high-performance, scalable single-photon detection in quantum communication,deep-space optical links, and astronomical observations require low-power, high-bandwidth cryogenic readoutsolutions, driving the need for an integrated photonic readout that mitigates power dissipation and enhancessystem scalability. Recent studies have demonstrated that photonic readoutsin cryogenic environmentsreduce power dissipation and increase bandwidth.The aim of this activity is to address the limitations ofhigh-power dissipation, large deadtime, and jitter in multipixelSNSPD arrays by integrating photonic readouts, within the cryogenic environment. This solution ensuresscalability of SNSPD arrays while maintaining optimal cooling and performance metrics and addresses marketneeds for stable, high-performance detectors in low-temperature environments.Procurement Policy: C(1) = Activity restricted to non-prime contractors (incl. SMEs).
