I want to design a ring resonator

[K. Esakki MuthuParticipant]

I want to design a ring resonator, i don’t know how to get that ring pattern into the Photonic crystal Structure. Also i couldn’t edit the individual cell parameter. Please help

Dear essakimuthu,

What kind of help u need and what kind of application will u prefer

[Damian MarekParticipant]

Hi,

I made a quick demo file for this. To get the ring pattern you can simply draw a Photonic Crystal and under the Crystal Lattice Properties add a new Ring Waveguide Unit Cell.

Is there any options to see the input waveform in fdtd and can u tell what are the parameters that can viewed at the output.

[Damian MarekParticipant]

In the example I attached I did not insert any input or detection objects, but when injecting a modal field you can solve the modes and then view them. With the detection objects generally you are looking at the electric and magnetic field components. There are of course plenty of parameters derived from the field, like the Poynting vector, normalized power, spectral density etc.

sir u sent me new version so can u please send the ring resonator in old version fdtd.

[Damian MarekParticipant]

Hi,

Unfortunately I can only support the most recent version, as it would be too hard to support all available versions of our software. However, the demo file I made is indeed quite simple. Try following the tutorial at:

PBG Layout

but instead of choosing Elliptic Waveguide as the unit cell, choose the Ring Waveguide.

dear I want to design the ring resonator as well but I need to put electrodes, any advice? still I am so confuse with this electrode story….
