ABSTRACT: We demonstrate two types of all-optical wavelength conversion devices using nonlinear optical effects in silicon photonic wire waveguides. One is based on cross-absorption modulation using two-photon absorption (TPA). The other is based on four-wave mixing and gives an internal conversion efficiency of about -11 dB. Conversion performances in both devices are degraded by free-carrier absorption (FCA) originating from the TPA. To eliminate FCA, we propose some techniques including lattice-defect implantations to reduce carrier lifetimeGroup IV Photonics, 2006. 3rd IEEE International Conference on; 01/2006

ABSTRACT: Efficient wavelength conversion via four-wave-mixing in silicon-on-isolator p-i-n waveguides has been realized. By reverse biasing the p-i-n diode structure formed along the silicon rib waveguide, the nonlinear absorption due to two photon absorption induced free carrier absorption is significantly reduced, and a wavelength conversion efficiency of -8.5 dB has been achieved in an 8 cm long waveguide at a pump intensity of 40 MW/cm2. A high-speed pseudo-random bit sequence data at 10 Gb/s rate is converted to a new wavelength channel in the C-band with clear open eye diagram and no waveform distortion. Conversion efficiency as functions of pump power, wavelength detuning, and bias voltages, have been investigated. For shorter waveguides of 1.6 cm long, a conversion bandwidth of > 30 nm was achieved.Optics Express 02/2006; 14(3):1182-8. · 3.55 Impact Factor
