Hi..

Is there any option to define electrodes in optiFDTD. My requirement is to control my photonic device using electric field. I have done it in optiBPM. Furthe I want to do it in optiFDTD. Please share the possibility of doing same in optiFDTD. Thanks in advance…

Hi Steve Dods..

Consider I am having a DC electric field, which can switch its state(either 0 V or 5 V) with the speed of 1 MHz. How can I apply this electric field to MZI electrodes and capture the response. From this I can test how fast the MZI is responding to the external electric field. Obviously the speed of light propagation is higher than the speed of electric field. But, i need to capture the response of MZI for the speed of external electric field. In this regard I need your help..

Thanks in advance

Hi Steve Dods..

The LN on insulator(Sio2) is used for low loss and better confinement. I have attached the files. Please suggest some ways to create layered profiles. I have tried using channel profile and adding layers in substrate option. The structure is created but it shows error while running the simulation. Often it shows violation error..

Thanks in advance..

Hi Steve Dods..

Thank you for your great answer. I have found in a sample file of OptiBPM ie. Magnesium doped waveguide is placed on top of the Titanium doped lithium niobate. The waveguide model is working, but the output electric field is decreasing in magnitude if we increase the length of the waveguide. I also tried to configure as directional coupler, but there is no coupling between two waveguides. We are mainly focusing on MgO:LiNbO3 wafers to develop our optical devices, hence I require this Mg doped LN waveguide.
