Small self-contained calculators I built because I got tired of re-deriving the same thing in a notebook. Everything runs in the browser; nothing is sent anywhere.

Two-ring filter Drop and through port spectra for a series-coupled double microring add-drop filter, from the exact transfer-matrix solution.
Ring modulator OMA Optical modulation amplitude, extinction ratio and insertion loss as a function of bias detuning and drive swing. The best bias for OMA is not the best bias for ER.
Vernier two-ring filter Two unequal rings in series. Composite free spectral range and side mode suppression as you detune the radii apart.
