Unmet Need: Efficient nonlinear light-matter interactions
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.
The Technology: Ultra-thin van der Waals crystal for efficient frequency conversion and phase matching
This technology introduces a periodically poled van der Waals semiconductor (3R-MoS2) as a new class of nonlinear optical crystal.
