Capacitively-Induced Free-Carrier Effects in Nanoscale Silicon Waveguides for Electro-Optic Modulation

Rajat Sharma, Matthew W. Puckett, Hung-Hsi Lin +3

We fabricate silicon waveguides in silicon-on-insulator (SOI) wafers clad with either silicon dioxide, silicon nitride, or aluminum oxide, and by measuring the electro-optic behavi…

Characterizing the effects of free carriers in fully-etched, dielectric-clad silicon waveguides

Rajat Sharma, Matthew W. Puckett, Hung-Hsi Lin +2

We theoretically characterize the free-carrier plasma dispersion effect in fully-etched silicon waveguides, with various dielectric material claddings, due to fixed and interface c…
