I am working on mode division multiplexing. I used a VCSEL component as an optical source. but I found the modulation bandwidth of this component is about 3GHz. is it true? how can I change the component parameters to increase its modulation bandwidth?

      Hollo,
      The bandwidth of the VCSEL laser can be controlled by adjusting the physical parameters that can be found in the component properties as shown in the image attached.
