In the current issue of Nature Photonics, Prof. Dr. Oliver G. Schmidt, Dr. Libo Ma and partners present a strategy for observing and manipulating the optical Berry phase in Möbius ring microcavities.

The micro-ring resonator, shown here as a closed loop, generated high-dimensional photon pairs. Researchers examined these photons by manipulating the phases of different frequencies, or colors, of ...

Resonators are devices that exhibit resonance, a phenomenon where a system oscillates with greater amplitude at specific frequencies. In the context of nanotechnology, resonators are nanoscale ...
