    "body_text": "Seoul National University and University of Seoul researchers proposed a coupled-resonator-induced-transparency circuit whose tunable couplings adjust both the delay and frequency content of optical signals. The design addresses buffering and synchronization problems in optical computing and communications. Its reported performance comes from computational simulation and modeling; the release does not describe a fabricated production chip, endurance test, or deployed optical memory.",
