We demonstrate high-speed silicon modulators optimized for operating at the wavelength of 2 μm. The Mach-Zehnder interferometer carrier-depletion modulator has a modulation efficiency (V π ·L π ) of 2.89 V-cm at 4 V reverse bias. It operates at a data rate of 25 Gbit/s with an extinction ratio of 6.25 dB.
