In most of the research work pertaining to SOI based Silicon Photonic waveguides, the standard thickness for the single mode waveguide is 220nm.
Could any one suggest about what is the largest thickness and cross section of SOI based silicon waveguide that is possible to operate in single mode?
*Any related literature/article would be very helpful.
Thank you!
The single-mode conditions depends also on the cladding refractive index. There are a lot of soft to calculate mode indices in wavegiuides (for example, COMSOL).
You also can use the following link to calculate modes of your waveguides

I think that one have to take into consideration the effective index that depends greatly on the dimension of the waveguide.
