Inverse designed photonic fibers and metasurfaces for nonlinear frequency conversion
Chawin Sitawarin, Weiliang Jin, Zin Lin +1
Typically, photonic waveguides designed for nonlinear frequency conversion rely on intuitive and established principles, including index guiding and band gap engineering, and are b…
Photon Torpedoes and Rytov Pinwheels: Integral-Equation Modeling of Non-Equilibrium Fluctuation-Induced Forces and Torques on Nanoparticles
M. T. Homer Reid, O. D. Miller, A. G. Polimeridis +3
We present new theoretical tools, based on fluctuational electrodynamics and the integral-equation approach to computational electromagnetism, for numerical modeling of forces and…
Topology Optimized Multi-layered Meta-optics
Zin Lin, Benedikt Groever, Federico Capasso +2
We propose a general topology optimization framework for metasurface inverse design that can automatically discover highly complex multi-layered meta-structures with increased func…
Enhanced nonlinear frequency conversion and Purcell enhancement at exceptional points
Adi Pick, Zin Lin, Weiliang Jin +1
We derive analytical formulas quantifying radiative emission from subwavelength emitters embedded in triply resonant nonlinear cavities supporting exceptional points (EP)…
Topology-optimized Dual-Polarization Dirac Cones
Zin Lin, Lysander Christakis, Yang Li +3
We apply a large-scale computational technique, known as topology optimization, to the inverse design of photonic Dirac cones. In particular, we report on a variety of photonic cry…
Topology optimization of multi-track ring resonators and 2D microcavities for nonlinear frequency conversion
Zin Lin, Marko Lončar, Alejandro W. Rodriguez
We exploit recently developed topology-optimization techniques to design complex, wavelength-scale resonators for enhancing various nonlinear and frequency conv…
