Oscillator Finite-Difference Time-Domain (O-FDTD) electric field propagation model: integrated photonics and networks

The recently developed Lorentz Oscillator Model-inspired Finite-Difference Time-Domain (O-FDTD) is one of the simplest FDTD models ever proposed, using a single field equation for electric propagation. We demonstrate its versatility on various scales and benchmark simulation performance against theory, conventional simulations, experimental observations. model’s broad applicability demonstrated (but not limited to) three contrasting realms: integrated photonics components nano- micrometer scale, city-wide propagating radiofrequency signals reaching into hundreds meters first time, in support 3D optical waveguide design that may play key role neuromorphic photonic computational devices.
