Abstract
In this Information Age, computers and mobile phones are important carriers of data transmission and many scientists work hard to speed up that process. Professor Peter Delfyett of the University of Central Florida has done just that. A member of the US National Academy of Engineering, he developed the world's fastest and most powerful mode-locked semiconductor laser. I have known Professor Delfyett since 2011, when he took part in the CIOMP-OSA International Summer Session. His sincere and friendly attitude, humorous and optimistic nature and excellent academic style left a deep impression. Driven by curiosity, human beings are constantly exploring the unknown, and asking questions. Einstein once suggested, defining what the problem is can be more important than solving it. And this is what Professor Delfyett has been advocating: pursue the ultimate academic goal, ask questions, believe in yourself and never give up. In addition, he has been striving to integrate industry and scientific research, so that scientific research results can truly benefit mankind. And now, please follow Light People to the latest cutting-edge progress in optics.
