The model uses 2D modal overlap with 2D carrier distribution across the waveguide to calculate the phase shifter performance metrics. The algorithm used to model the 2D nature of the PN diode depletion region is presented in detail and uses mathematical and analytical formulas instead of numerical methods, making the model faster and easy to implement, with accuracy on par with commercial tools.Two types of phase-shifting algorithms were developed for simultaneous measurement of the surface and thickness variation of an optical flat.
