Question 10 of 11
10. Question
Download and open the file INT_QE_Ring_Modulator.icp. This simulation file contains a simple ring modulator circuit with no analyzer. We will follow the name convention for the ports as described in this picture:
- Add an Optical Network Analyzer (ONA) to the circuit. Set the number of inputs to 2.
- Connect its output to the input port of the ring modulator, input 1 to the through the port, and input 2 to the drop port.
- Set the simulation so the frequency range of the ONA is 1THz and run the simulation.
- Adjust the simulation settings to resolve the warning message.
Plot abs(transmission)^2 from the drop port. What is the free spectral range of the ring modulator? Insert your answer as a number of TeraHertz [THz] with one decimal place precision. For example, if the answer is 0.224THz, type in 0.2.

Question 11 of 11
11. Question
Change the amplitude of the DC source to -5V and run the simulation again. What is the magnitude of the shift in the resonance frequency? (Insert your answer as a number of gigahertz [GHz] with no decimal place precision. For example, if the answer is 50.2GHz, type in 50).
(Hint: Plot abs(transmission)^2 of the drop port on the same graph.)
