Pump source

[Kumar]

Sir / Madam,

Greetings,

I want to model a particular geometry of nonlinear photonic crystal modulator i.e., optically controlled modulator. For that, I have a doubt is that how to apply the pump intensity (laser light source) to the particular doped crystal (hole). It is possible in Opti-FDTD software. Could you please provide some document related to that.

Thanks.

Hello Kumar,

OptiFDTD does provide the means for modelling some non-linearity effects, specifically 2nd order and Kerr (3rd order). We would need to know more about the nature of your simulation to provide more assistance.

1. When you refer to a doped crystal are you referring to doping the material crystal (i.e. doped silicon) or do you mean you are back filling the holes with a second material? Also if it is a doping of your device layer what are you doping it with?

2. What nonlinear effect are you using for this particular device?

Regards,
Scott
