Computer aided design (CAD) tools can expedite the development of high speed electrooptic modulators. The simulation program can be used to simulate the device performance, therefore, lead to the optimal design. The layout tool can be used to design mask patterns. Custom features specifically developed for electrooptic modulators make the mask pattern design highly efficient. The OPTOMASK layout program and results of simulations on low-loss Y-branch design and on quasi-linear electrooptic modulator design are reported.
