Overview of Frequency Domain Simulations in Ansys Lumerical INTERCONNECT — Lesson 1


Frequency domain simulations are useful in studying photonic circuits in a steady-state. In this video lesson, you will learn about the basics of the frequency domain simulations in Ansys Lumerical INTERCONNECT.


Example Uses of Frequency Domain Simulations

Here are some of the typical application examples using frequency-domain simulations. See the “Related Links” for further information.

Straight Waveguide

In this example, the frequency-domain solver is used to obtain the frequency response of a waveguide. The simulation results of interest include the transmission power and phase, as well as the group delay and group velocity.

Ring resonator in steady-state

In this example, INTERCONNECT is used to build a double bus ring resonator circuit. Frequency-domain simulation is used to determine the response of the system as a function of the frequency/wavelength at the drop and through ports.

Ring modulator DC response

Ring modulators are tunable ring resonators. In this example, frequency-domain simulations are used to determine the frequency response of the ring modulator as a function of the modulation input voltage.

Fabry-Perot in steady-state

In this example, a frequency domain simulation is used to obtain the transmission spectrum of the Fabry-Perot etalon.
