UrduGreen-gap lasing is a grand challenge that nonlinear nanophotonics has promise to address. Our research advances this by using Kerr optical parametric oscillation in silicon nitride microrings, pumped with a tunable 780 nm laser, to access the entire green gap (532-633 nm).

Molybdenum Disulfide Ushers in Era of Post-Silicon Photonics
Researchers of the Center for Photonics and Two-Dimensional Materials at MIPT, together with their colleagues from Spain, Great Britain, Sweden, and Singapore, including co-creator of the world’s first 2D material and Nobel laureate Konstantin Novoselov, have measured giant optical anisotropy in layered molybdenum disulfide crystals for the first time. The scientists suggest that such transition metal dichalcogenide crystals will replace silicon in photonics. Birefringence with a giant difference in refractive indices, characteristic of these substances, will make it possible to develop faster yet tiny optical devices. The work is published in the journal Nature Communications.
