A cryogenic wavelength-multiplexed optical-to-microwave converter draws RF-photonics interest
The post points to a Bisang2026 paper on a cryogenic wavelength-multiplexed eight-channel optical-to-microwave converter.
The accompanying comment is a practical RF-photonics take: after the usual “put everything on-chip” phase, the harder questions become efficiency, light leakage, heat, and actual plumbing.
In other words, the discussion is about the engineering reality of cryogenic RF/photonics systems, not just a flashy concept demo.
