I. Spin-orbit interactions of light. We study - both theoretically and experimentally - the interplay between spin and angular momenta of light in different nanophotonic platforms, aiming to uncover new phenomena that arise from complex interactions or different symmetry.

II. Spatial photonic Ising machines. Light-based simulator for complex XY spin interactions and solving quadratic unconstrained binary optimization problems. 

Spatial photonic Ising machines are inherently limited to all-to-all spin interactions, restricting their ability to model complex physical systems. To address this, we developed an optical spin model simulator that enables distance-dependent spin interactions by modulating light in momentum space. Using a laser beam and a phase-only spatial light modulator, the system reproduces complex magnetic states and topological phase transitions, enabling new possibilities for simulating spins and topological effects in physics and materials science.

III. Nanophotonics (metasurfaces and photonic crystals). We design novel metasurfaces and photonic crystals with unique physical properties for potential applications in advanced light emission, manipulation, and detection.

We demonstrate a nearfield vortex dynamic within a supercell photonic crystal. By introducing paired rotations of triangular structures, we achieve high-quality-factor Bloch mode transition from evanescent valley modes, to quasi-bound states in the continuum, frustrated modes, and quasi-valleys. Each stage exhibits distinct nearfield vortex distributions, nonlinear overlap properties, and quality factors, revealing diverse physical behaviors for tailoring light-matter interaction. Notably, the asymmetric vortex configuration of frustrated modes enhances second harmonic generation, driven by an optimized nonlinear overlap factor. Our paired-rotation strategy offers a versatile design framework for creating supercell photonic crystals with unique nearfield vortex properties, presenting promising applications in lasing, nonlinear optics and optical forces. arXiv preprint arXiv:2412.00698
