We present the heterogeneous integration of InP/InGaAsP photodetectors onto ultracompact Silicon-on-Insulator (SOI) waveguide circuits using benzocyclobutene (BCB) die to wafer bonding. This technology development enables the integration of a photonic interconnection layer on top of CMOS. Fabrication processes were optimized and the transfer of a passive… (More)
—We demonstrate a very compact multifunctional pho-tonic-crystal demultiplexer on high index contrast InP-membrane for coarse WDM applications. Polarization diversity is implemented using 2D-grating couplers. The performance of the device is evaluated using integrated p-in photodetectors. Polarization diversity from fiber to detector—without intermediate… (More)
—We review recent progress in opto-electronic components and circuits for optical interconnect networks based on a silicon based photonic wire technology. We discuss the transmitter part, the receivers and the integration with electronics.
Stimulated Brillouin scattering was recently observed in nanoscale silicon waveguides. Surprisingly, thermally-driven photon-phonon conversion in these structures had not yet been reported. Here, we inject an optical probe in a suspended silicon waveguide and measure its phase fluctuations at the output. We observe mechanical resonances around 8 GHz with a… (More)
In this work we present results from high performance silicon optical modulators produced within the two largest silicon photonics projects in Europe; UK Silicon Photonics (UKSP) and HELIOS. Two conventional MZI based optical modulators featuring novel self-aligned fabrication processes are presented. The first is based in 400nm overlayer SOI and… (More)
Silicon-on-insulator (SOI) is rapidly emerging as a versatile platform for a variety of integrated nanophotonic components. High density waveguide circuits can be fabricated using standard CMOS processing techniques. However, light detection in the near-infrared wavelength range (1550 nm) is not possible in silicon which is naturally transparent in this… (More)
