The performance of photodetectors fabricated from emerging semiconductors such as perovskites, quantum dots, two-dimensional materials or organics, for example, can be prone to misinterpretation. This Comment exposes the problems and proposes some guidelines for accurate characterization.
Optical fibre technology transformed telecommunications, leading to the global broadband Internet, and beyond. Charles Kuen Kao is the father of optical fibre communications whose vision changed the world.
Emil Wolf died in June 2018 at the age of 95. The father of optical coherence theory was at the University of Rochester for nearly 60 years. A memorial in August at the university attracted more than 150 attendees from around the world.
Innovations in ‘sustainable’ photonics technologies such as free-space optical links and solar-powered equipment provide developing countries with new cost-effective opportunities for deploying future-proof telecommunication networks.
Nicolaas Bloembergen made rich contributions to nuclear magnetic resonance, masers and lasers, nonlinear optics and ultrafast laser–matter interactions. The Nobel laureate sadly passed away on 5 September 2017. Here are my memories of my Harvard mentor, a remarkable person and a wonderful scientist.
