  • EFFICIENT FREQUENCY CONVERSION VIA PHOTONIC RESONANCES NEAR BOUND STATES IN THE CONTINUUM
    Publication number: 20250020970
    Abstract: Methods and systems are described for conversion of an optical signal. The device may comprise a conversion layer comprising a nonlinear optical material with a surface structure disposed to receive a pump signal and cause a bound states in the continuum (BIC) optical mode. The conversion layer may be configured to convert, based on nonlinear interaction with the BIC optical mode, an incoming signal incident on the conversion layer from an incoming wavelength to a target wavelength.

  • Nonlinear on-chip optical devices using AlScN
    Patent number: 12117713
    Abstract: Nonlinear on-chip optical devices using AlScN are described herein. In one aspect, an optical component having nonlinear characteristics can include a first substrate defining a refractive index; and a nonlinear layer, the nonlinear layer disposed on the first substrate, the nonlinear layer comprising an amount of scandium (Sc), and the nonlinear layer defining a refractive index that is higher than the refractive index of the first substrate.
