—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 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)
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)
─We present the design and simulation results of an integrated wavelength demultiplexer. The device's major components, which include the Silicon-on-insulator (SOI) etched diffraction grating and waveguide integrated InP/InGaAs MSM photodetectors are discussed in detail. The Silicon-on-insulator diffraction grating is fabricated using standard CMOS(More)
