ResumoWe demonstrate a highly integrated micrometer-scale low-power wavelength converter based on the free-carrier dispersion effect in silicon. The conversion is achieved through all-optical modulation of a silicon ring resonator by use of modulated cw control light. The ring resonator has a radius of 5??m and a Q of ?10,000. Both inverted and noninverted modulation are achieved at a bit rate of 0.9?Gbits?s with a control power of 4.5 mW. The scaling of the required control power for operation with respect to the characteristics of the ring resonator is established.
