Small, self-contained simulations for teaching and exploring photonics, from undergraduate optics to research-level nonlinear cavity dynamics. Everything runs in your browser: no install, no server, and you can open any page offline.
One- and two-port Fabry–Pérot and ring resonators in temporal coupled-mode theory, with thermo-optic (red shift) or free-carrier (blue shift) nonlinearity. Watch the laser follow the stable branch and the hysteresis appear.
Linearized optomechanics read out on an ESA. Transduction vs detuning in the resolved and unresolved sideband regimes, thermal bistability during laser sweeps, converting PSD (dBm) to displacement, optical spring and damping vs power, sideband cooling and OMIT.
