The field of all‐optical logic circuits has garnered significant attention in recent years, particularly with the integration of micro‐ring resonators to process information entirely via light.
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.
Optical ring resonators. Closed bands or rings also play an important role in optics and optoelectronics. Until now, however, they have not consisted of Möbius strips and they are not made of ...
