We present measurements of the nonlinear distortions of a traveling-wave silicon Mach-Zehnder modulator based on the carrier depletion effect. Spurious free dynamic range for second harmonic distortion of 82 dB·Hz 1/2 is seen, and 97 dB·Hz2/3 is measured for intermodulation distortion. This measurement represents an improvement of 20 dB over the previous best result in silicon. We also show that the linearity of a silicon traveling wave Mach-Zehnder modulator can be improved by differentially driving it. These results suggest silicon may be a suitable platform for analog optical applications. © 2013 Optical Society of America. Source

We report optical waveguides up to one meter long with 0.026 dB/cm loss fabricated in a 300nm thick SOI CMOS process. Combined with tight bends and compact interlayer grating couplers, we demonstrate a complete toolbox for ultralow-loss, high-density waveguide routing for macrochip interconnects. © 2012 Optical Society of America.

We report the first compact silicon CMOS 1×4 tunable multiplexer/ demultiplexer using cascaded silicon photonic ring-resonator based add/drop filters with a radius of 12μm, and integrated doped-resistor thermal tuners. We measured an insertion loss of less than 1dB, a channel isolation of better than 16dB for a channel spacing of 200GHz, and a uniform 3dB pass band larger than 0.4nm across all four channels. We demonstrated accurate channel alignment to WDM ITU grid wavelengths using integrated silicon heaters with a tuning efficiency of 90pm/mW. Using this device in a 10Gbps data link, we observed a low power penalty of 0.6dB. © 2010 Optical Society of America. Source
