11月5日，应深圳大学物理与光电工程学院何俊教授邀请，塞浦路斯理工大学PhOSLab主任、光子学Kyriacos Kalli教授到访广东省光纤传感技术粤港联合研究中心（COFS），作以“A perspective on the evolution of advanced photonic sensing and communication”为题的高水平学术专题报告，中心众多师生积极到场参会交流。
报告伊始，Kalli教授回顾了自己三十余年在光纤传感领域深耕的早期基础研究成果，围绕飞秒激光制备各类光纤布拉格光栅的前沿思路与技术路线展开分享。针对光纤传感领域普遍存在的交叉敏感难题：普通光纤传感器易同时受到温度、应变等多种物理量耦合干扰，难以实现单一参量精准测量，Kalli教授介绍了团队的参量解耦调控技术方案。团队通过对聚合物光纤实施预应变改性处理，实现传感响应的选择性优化，让聚合物光纤传感器可特异性对温度信号响应，抑制其他物理参量带来的信号串扰，解决多物理量交叉敏感痛点。
随后，Kalli教授介绍该类改性聚合物光纤传感器在生物医学健康监测、辐射监测方向的落地应用。其中重点展示面向脑科学研究的在体急性脑温实时监测技术，利用微型化光纤传感探头开展活体脑部温度原位测量，为脑疾病研究提供新型检测手段。除光纤传感方向外，报告还拓展到量子通信前沿，介绍团队牵头的塞浦路斯地面量子密钥分发（CYQCI）项目，以及参与欧盟跨国卫星量子密钥分发SEEWQCI项目的最新进展，围绕城域、卫星安全量子通信网络发展演进进行分享。为在场师生带来光子传感-量子通信交叉方向的全新视野。
报告结束后，何俊教授、徐锡镇副教授向Kalli教授详细介绍COFS中心科研进展，重点展示本中心在飞秒激光加工光纤光栅的制备工艺、器件开发以及多场景传感应用的技术积累。双方围绕特种光纤传感、飞秒激光光栅制备、双光子聚合3D打印技术等共同关心的科学问题展开深入研讨，交换技术思路，探讨未来潜在合作方向，有力推动两个科研团队的学术对接。
本次来访与学术报告活动，拓宽了中心师生的国际学术视野，促进了光纤传感、量子光子领域的中外学术思想碰撞，进一步推进COFS中心国际交流合作建设，为后续开展跨国联合研究、人才互访夯实基础。
报告摘要：This lecture will present several ideas and concepts that have been employed to advance optical fibre sensing and filtering based on femtosecond lasers for the fabrication of various fibre Bragg gratings. It will discuss customised multi-parameter sensors, including their applications in brain sensing through acute in-vivo measurements, the development of compact monolithic fibre lasers, and mid-infrared sensing. In addition, it will cover recent progress and advances in secure metropolitan and satellite communication networks enabled by QKD.
