Application Gallery

The passive components getting started guide provides several tutorials with step by step instructions on how to simulate a variety of passive components. An introduction to the basic functionality of the relevant solver is given followed by application specific examples. All simulation and script files used in the tutorials are available for download.

Passive component design


Ring resonator MODE (design and initial simulation)

The example will show how to design and simulate a ring resonator using the FDE solver 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.


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

Ring resonator MODE (parameter extraction and Monte Carlo analysis)

This example will use the initial design introduced in Ring Resonator (design and initial simulation) to perform additional analysis with the varFDTD solver.


The user will learn to:

Use Mode Expansion Monitors to extract the parameters for interfacing with circuit level simulations in INTERCONNECT.

Compare the S parameter results with 3D FDTD.

Use the Monte Carlo Analysis feature to track the effect of fabrication errors on the free spectral range (FSR) of the ring resonator.


Ring resonator FDTD (final parameter extraction with 3D FDTD)

The example will show how to set up the same ring resonator simulation in 3D FDTD and extract the S parameter results.


Ring Resonator INTERCONNECT (circuit simulation)

See how to design and simulate a ring resonator using INTERCONNECT.





Spot size converter

This example will show how to design and simulated a spot size converter that can efficiently couple light from a strongly confined high index contrast silicon waveguide into an optical fiber, using the EME solver.


The user will learn to:

Set up an EME simulation

Quickly scan the length of the spot size converter to find the optimal design

Compare results with 3D FDTD results
