First demonstration of SiGe-based carrier-injection Mach-Zehnder modulator with enhanced plasma dispersion effect.We demonstrate a strained Si0.91Ge0.09-based carrier-injection Mach-Zehnder (MZ) optical modulator using the enhanced plasma dispersion effect in strained SiGe through mass modulation for the first time.
