4. Design a component: MMI¶
In this session, you will learn how to design a multi-mode interferometer (MMI) in three steps. The first step is writing the PCell describing the layout of the MMI. Then, a circuit model is added to the MMI to run simulations using CAPHE. Last, the MMI is optimizes using CAMFR, the 2D mode solver built-in in IPKISS.
