Assistance Needed for Wavelength Adjustment in Optical Ring Modulator Simulation

      Dear Ansys Support Team,

      I am Abhishek Kumar Anand, currently an MTech student in Communication Systems and Signal Processing at IIT Patna. I am working on a simulation project involving the Optical_Ring_Modulator.icp in Ansys Electronics Desktop, which is currently set for a wavelength of 1310 nm. However, I need to adjust this simulation to operate at 1550 nm.

      I would greatly appreciate guidance on making the necessary adjustments to accommodate this wavelength change. Specifically, I am looking for advice on any modifications required for the neff_vs_voltage_11.txt file, and adjustments to the ring modulator’s physical parameters, such as length and radius, to ensure accurate simulation results at 1550 nm.

      Thank you very much for your assistance and insights. I look forward to your response.

      Best regards,

      Hi Abhishek,

      Optical_Ring_Modulator.icp  is a Lumerical INTERCONNECT file. In its layout mode, you can click the cwl source tab, and modify its wavelength as desired. You can modify the paprameters for all other elements in the layout mode.

      Dear Guilin Sun,

      To achieve correct modulation, it is essential to select an accurate neff_vs_voltage_11.txt file corresponding to the target wavelength, in addition to adjusting the radius and length of the ring modulator. These parameters are critical to ensure efficient operation at 1550 nm, as they directly affect the phase shift and coupling characteristics necessary for optimal modulation performance.

      If possible, providing an icp file specifically configured for 1550 nm would simplify this process. Such a file would contain the required values and preset parameters, ensuring a more reliable setup for precise simulation and performance at the specified wavelength.
