Online Ring Resonator Simulator
Coupled microring modelling with live spectra - drag a coupling coefficient, watch the resonance move.
Launch the tool →An interactive simulator for microring resonator filters based on exact transfer-matrix modelling. Configure one to five coupled rings, set coupling coefficients, losses, and radii, and get transmission spectra, phase response, group delay, and dispersion in real time as you drag parameters.
Useful for building intuition on add-drop filters and coupled-resonator devices: see how coupling strength trades off with extinction and bandwidth, how loss rounds off resonances, and how multi-ring arrangements shape flat-top pass bands.
Everything runs client-side with instant feedback, and results export to JSON.
