This technology is an ultrathin periodically poled van der Waals semiconductor (3R-MoS2) that enables efficient broadband quasi-phase matching, high-frequency conversion efficiency, and seamless integration into optical circuits.
Nonlinear optics are essential for classical and quantum sources of radiation, enabling fundamental spectroscopy and optical information processing. Efficient nonlinear light-matter interactions remain challenging for classical and quantum radiation sources. Conventional approaches rely on birefringent crystals like lithium niobate, but their macroscopic thickness limits integration with optical circuits.
This technology introduces a periodically poled van der Waals semiconductor (3R-MoS2) as a new class of nonlinear optical crystal. Its ultra-thin 1 µm thickness allows seamless integration with optical circuits and compact device design, overcoming the limitations of current macroscopic nonlinear crystals. It enables broadband quasi-phase matching and, with exceptional nonlinearity (100–1000 pm/V), achieves record-high frequency conversion efficiency at telecom wavelengths. This microscopic van der Waals crystal holds potential for phase-matched nonlinear optics in on-chip quantum photonics, telecommunications, laser technology, and quantum optics.
