the width and height of the waveguides

      Dear all,

      I am working with a ring resonator in Lumerical Mode. The width and height of the waveguides: 0.4 and 0.18 microns. But when I change it to 0.5 and 0.22 microns there is no resonance.

      My question is: why is it happening?


      Thanks in advance!

      Hi Lizzie_Leon
      It is really hard to tell about the problem with the limited information. Could you please provide some more details on this? For example some screenshots and what's your struture looks like and how you set it up. Thank you.

      So when I only change the base width and height to 0.5 and 0.22 there is no resonance. Nothing in the drop port.

      Is this referring to a specific example on our website? I have to know your design to be able to tell the problem.

      No. Just a simple design of a ring resonator. When the base width and height are 0.4 and 0.18, there is no problem and one can see the signal at the drop port. But once the width and height of the waveguides are changed to 0.5 and 0.22 there is no resonance.
