Abstract :
We demonstrate an optical link on silicon employing Ge/SiGe quantum well waveguide modulators and photodetectors. Modulators show >3 dB contrast ratio for <6 V drive for a 22 nm wavelength range. Photodetectors show external responsivity up to 0.26 A/W and high-speed detection at 2.5 Gb/s.
