This technology is an ultra-compact transition metal dichalcogenide with a rhombohedral stacked configuration of Molybdenum Disulfide for use in optical quantum circuits.
Transition metal dichalcogenides (TMDs), such as MoS2 (Molybdenum Disulfide) have very high nonlinear optical coefficients and hold promise to enable efficient light frequency conversion with minimal footprint. TMDs can be used with either monolayered structures or as multilayers, but both approaches are limited in efficiency. Monolayers exhibit a low conversion efficiency and multilayers forming bulk crystals result in inversion symmetry and a loss of nonlinear optical properties otherwise needed. Thus, there is a need for compact nonlinear optical conversion technologies with TMD structures that do not compromise efficiency.
This technology utilizes a non-centrosymmetric stable polytype for multilayer configuration in the form of rhombohedral MoS2 (3R-MoS2). This technology provides a model that explains the nonlinearity dependence on material thickness of 3R- MoS2. Properties such as a birefringent refractive index and low-loss anisotropy were also characterized, thus optimizing the optical signal and conversion efficiency of the TMD.
