Adaptive Profile Poling of Nanophotonic Lithium Niobate Waveguides for High Overall Nonlinear Efficiency
Innovators at the University of Arizona have overcome the non-uniformity issue of thin-film Lithium Niobate. Adaptive profile poling is promising to realize high nonlinear efficiency with strong material second-order nonlinearity. Nonlinear efficiency can actually increase quadratically with length using this method.
It was shown that the optical momentum...

Photonic Machine Learning with Wavelength/Frequency Multiplexing
This invention is an improved method of machine learning utilizing nanophotonic devices to implement neural networks. Photons from nanophotonic devices have degrees of freedom which allow for more information to be encoded in the photons. This allows the neural network to be expanded. Signals then are encoded in different wavelengths which allow for...
