We present first experimental results of a high-speed silicon optical modulator based on carrier depletion in interleaved PN junctions oriented in the waveguide direction. The modulator is integrated in a ring resonator of radius 50 μm. The modulator is characterized using a laser beam at 1.55 μm for TE and TM polarizations, and extinction ratios as high as 11 dB and 10 dB in in TE- and TM-polarizations, respectively, obtained between 0 and -10 V. At 10 Gbit/s extinction ratios of 4.1 dB and 2.7 dB for TE- and TM-polarization, respectively, are experimentally demonstrated.
