Ring resonator MODE (design and initial simulation)

Scroll Prev Top Next More

This is Part 1 of the ring resonator getting started tutorial. Here, we will consider how MODE can be used to design and simulate a ring resonator. We will use the software to achieve a desired free spectral range (FSR) and quality factor (Q factor) for a silicon on insulator (SOI) based waveguide design targeting on-chip communication applications. In Part 2, Ring resonator (parameter extraction and Monte Carlo analysis),  we will consider how to carry out the parameter extraction and Monte Carlo analysis process for this design.

Learning objectives

In this example, we show how MODE can be used to design a ring resonator.  The user will learn to:

Insert a ring resonator object from the components library

Use the Eigenmode Solver to choose the waveguide spacing, coupling length and ring length for the desired FSR and Q factor

Compare results with the theoretical design and 3D FDTD results
