The team at EPFL's Photonic Systems Laboratory (PHOSL) has developed a chip-scale laser source that enhances the performance of semiconductor lasers while enabling the generation of shorter ...

Whispering gallery modes, a type of wave that can travel around concave surfaces, have proved to be promising for the development of new technologies, particularly in photonics. Due to geometrical ...

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 ...

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 ...
