“…In [18], the phase shifter is a part of Mode selecting switch to select one of the two outputs; TE0 mode or TE1 mode to exit from the MMI. In [19,20] the phase shifter with a butterfly-shape is used in the design of a 2D mode converter to enable the excitation of the LP21 fiber mode. In this work we develop design formulas for the optical phase shift between two waveguides of the same length, one is used as a reference guide and the other creates the required phase change.…”

In this paper, we introduce simple design equations for optical phase shifter configurations on both single mode and multimode platforms. The design equations are based on approximate mathematical expressions describing the phase shift (difference) between two waveguides, one is considered as the reference guide and the second is considered as the phase shifter. Different layout geometrical configurations have been studied: the step width and the linear tapering waveguide. The validity of the design formula is tested using standard Beam Propagation Method BPM. The obtained results are in good agreement with numerical calculations and allow using these closed form expressions in the optical design of such phase shifters.
