Here we use spatiotemporal imaging to provide phase-matching angles, mode profiles and losses in 3R-MoS2 waveguides, showing birefringent phase matching in both multi- and single-mode waveguides.

Here we realize ultracompact entangled photon sources by periodically poling 2D semiconductors (3R-MoS2), demonstrating quasi-phase-matched up- and down-conversion over micron-thick pathlengths.

Quasi-phase-matched up- and down-conversion in periodically poled layered semiconductors - Nature Photonics
Researchers created a periodically poled van der Waals semiconductor (3R-MoS2) and achieved a macroscopic frequency conversion efficiency of 0.03% over a thickness of 3.4 μm. The quasi-phase-matched s...
