—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)
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)
Using InP and PbSe quantum dots, we demonstrate that the Langmuir-Blodgett technique is well-suited to coat nonflat surfaces with quantum dot monolayers. This allows deposition on silicon substrates covered by a developed patterned resist, which results in monolayer patterns with micrometer resolution. Atomic force microscopy and scanning electron… (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)
