Strong Polarization-Tuned Optical Nonlinearity Via Femtosecond-Laser Plasmonic Nanolithography in Lithium Niobate (Small 25/2025)
Hybrid Plasmonic Materials
Incorporating nanoparticles into lithium niobate-based photonic platforms to enhance performance and control near-field light presents significant challenges. In article number 2411607, Xiaoli Sun, Saulius Juodkazis, Feng Chen, and co-workers successfully developed a gold nanorod-lithium niobate hybrid plasmonic structure using plasmonic nanolithography. This innovative hybrid plasmonic material demonstrates remarkable polarization-dependent nonlinearity, particularly showing a substantial increase in the nonlinear absorption coefficient—by five orders of magnitude—for light polarized along the long axis of the nanorods.
