They’re full of fascinating engineering, but for my money, the inline optical repeaters that boost the signals along the way are the most interesting bits, even though — or perhaps especially ...

We review basic principles of modern optical magnetometers, discuss fundamental limitations on their performance, and describe recently explored applications for dynamical measurements of ...

Optical parametric oscillators simultaneously generate two beams of coherent light that are widely tunable in wavelength. This flexibility makes them a popular tool in various areas of scientific ...
