    I am attaching a screenshot to clarify my question. I am simulating this laser and I want it to have a modulation bandwidth of 7.75 GHz. I am performing the simulation in sweep mode from 200 MHz to 15 GHz with a step of 200 MHz. However, I always get an ideal bandwidth. I am attaching a comparison with a MATLAB plot showing the desired results.

    Sorry, I was referring to 7.75 GHz as the modulation bandwidth, not the spectral linewidth. Can you tell how can I set the modulation bandwidth of the DML??
