Spin–orbit optical phenomena involve the interaction of the photon spin with the light wave propagation and spatial distribution, mediated by suitable optical media. Here we present a short overview of the emerging photonic applications that rely on such effects.
The concept of optical computing is reintroduced with an important new twist — optical computing not as a digital machine, but as an analog engine able to serve as a hardware accelerator for existing electronic computers.
The use of photonics technology is bringing new capabilities and insights to cardiovascular medicine. Intracoronary imaging and sensing, laser ablation and optical pacing are just some of the functions being explored to help diagnose and treat conditions of the heart and arteries.
SESAME is a 2.5 GeV third-generation light source under construction in Jordan. Commissioning will begin in the second half of next year, assuming the funding that is still needed can be found.
Charles Townes, the Nobel laureate acclaimed for his pioneering work on lasers and nonlinear optics, sadly passed away in January this year. Here I offer personal reflections of working with him as one of his graduate students.
