In this example, we will demonstrate how INTERCONNECT can be used to design and simulate a Fabry-Perot resonator.

The Fabry-Perot etalon is the most basic optical resonator. The varying transmission function of an etalon is caused by interference between the multiple reflections of light between two reflecting surfaces:
There are two basic ways to simulate a Fabry-Perot resonator in INTERCONNECT. We can start by adding two optical mirrors and a straight waveguide from the element library to the schematic editor to construct the Fabry-Perot cavity.
Alternatively, we can also use the Fabry-Perot Resonator element from the element library to model the resonator directly:
