A re-entrant chip-free-space photonic interface for telecom-to-Rubidium spectroscopy
Jia-Lin Chen, Ruixin Zhou, Deng-Hong Liu +13
The paper presents a re‑entrant chip‑free‑space interface where a thin‑film lithium niobate photonic circuit frequency‑doubles telecom light to 780 nm, sends it through a rubidium…

Photorefractive-based on-chip optical power limiter against light-injection attacks in quantum key distribution
Min Chen, Hong-Yan Song, Jia-Lin Chen +10
Light-injection attacks pose critical security threats to quantum key distribution (QKD) systems. Conventional countermeasures, such as isolators, filters, and optical power monito…
