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. These ...
EPFL researchers have developed a hybrid device that significantly improves existing, ubiquitous laser technology. The team at EPFL’s Photonic Systems Laboratory (PHOSL) has developed a chip-scale ...

0Green laser pointers have existed for 25 years, but they produce light only in a narrow spectrum of green and are not integrated in chips where they could work together with other devices to perform ...
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 ...
