Light People: Professor Xianfeng Chen spoke about integrated photonics

In 1969, Stewart E. Miller published "Integrated optics: an introduction", which outlined a proposal for a miniature form of laser beam circuitry, marking the first research paper about what is now known as integrated photonics. Now half a century has passed, integrated photonics grew robustly from integrating a limited number of devices and functions towards versatile and industrialized photonic integrated circuits. In this interview, Light: Science & Applications invited Prof. Xianfeng Chen [see the "Short Bio" section] to share his insight about the past, present and future of integrated photonics.
