How can I approximate the Poynting Vector in a slot waveguide for a TE mode, in COMSOL?

The design of an optical slot waveguide typically aims to achieve an intensity of a x-component of the E-field that is much higher than the other components, leading to a quasi TE-condition. In...

What has the highest priority in the design of a slot waveguide EO modulator between the effective area and the optical confinement factor ?

I'm having a long discussion with my boss concerning with the optimal design of a slot waveguide EO modulator. He considers that the maxmization of the optical confinement factor into the slot has...

What is the proper area to refer for the Optical Confinement Factor in Slot Waveguide Modulators ?

In order to optimize the design of an EO modulator the maximum overlap of the RF electric field to the optical field must be achieved. In a Slot waveguide it implies the overlap must be achieved...

Would you suggest Lumerical instead of COMSOL for design of Slot waveguide modulators ?

Does Lumerical allows for calculation of the field profile for both the optical and the RF electrical fields ? COMSOL is powerful for that and allows for optimization of the fields overlap, as...

Hints or tricks to design a Slot waveguide photonic modulator with COMSOL as a COMSOL beginner ?

After reading some papers on photonic organic modulators, I started evaluation of COMSOL to optimize the overlap of the RF electrical field and the optical field of the travelling wave.The layout...

Is there a dependance of the Refractive index dispersion in p-type or n-type Silicon on the doping concentration ?

I need to optimize a strip loaded slot waveguide based on Silicon cores and to do that I need to set the refractive index of the p-type Silicon I am going to use, in order to understand how much...

In the layout optimization of an EO Modulator, is the effective area to be optimized related to the optical field or to the applied electric field ?

I have to design the layout of an electro-optic modulator using a slot waveguide structure. In the papers from Christian Koos (Karlsruhe Institute of Technology), in particular Optics Express 15,...
