Discovery of a novel silicon photonic crystal waveguide modulator. Ray Chen. Photonic-crystal waveguides that significantly slow light have been exploited to make a silicon modulator with an interaction length of 80?m and a peak drive current of less than 150?A. 10 April 2006, SPIE Newsroom. DOI: 10.1117/2.1200602.
An ultracompact silicon electro-optic modulator was experimentally demonstrated based on silicon photonic crystal (PhC) waveguides for the first time to our knowledge. Modulation operation was demonstrated by carrier injection into an 80?m-long silicon PhC waveguide of a Mach-Zehnder interferometer (MZI) structure.
Exploiting the slow group velocity of light in photonic crystal waveguides, the interaction length of this Mach-Zehnder interferometer-type silicon modulator is reduced significantly compared to conventional modulators. The required high current density is achieved with a low voltage (2V) by scaling down the interaction

In addition to the advantages associated with the slow group velocity, photonic crystal waveguide modulators are found to exhibit other structural and optoelectronic merits for high speed modulation. We also briefly review past work on silicon modulators and present certain speed scaling of silicon modulators. The scaling is
Ultra-compact silicon-photonic-crystal-waveguide-based thermo-optic and electro-optical Mach-Zehnder interferometers have been proposed and fabricated. The.
