Abstract :
We have demonstrated the fabrication of Ge-rich SGOI wafer by Ge condensation and regrowth technique to en-hance free carrier plasma dispersion for waveguide optical modulators. The Ge-rich SGOI was successfully fabricated without any thick buffer layers. The presented fabrication process is CMOS compatible and highly promising for high-performance SiGe optical modulators.
