Hybrid Integration of modified uni traveling carrier photodiodes on a multi layer silicon nitride platform using total reflection mirrors
Optics Express, 2017Co-Authors: Yang Shen, Kuanping Shang, Shaoqi Feng, Jizhao Zang, Siwei Li, Tiehui Su, J C CampbellAbstract:We demonstrate Hybrid Integration of modified uni-traveling carrier photodiodes on a multi-layer silicon nitride platform using total reflection mirrors etched by focused ion beam. The Hybrid photodetectors show external responsivity of 0.15 A/W and bandwidth of 3.5 GHz for devices with a diameter of 80 µm. The insertion loss of the waveguide is 3 dB and the coupling efficiency of the total reflection mirror is −3 dB. The highest RF output power is −0.5 dBm measured at 3 GHz with 9 mA photocurrent and −9 V bias.

Silicon-Organic Hybrid (SOH) and Plasmonic-Organic Hybrid (POH) Integration
Journal of Lightwave Technology, 2016Co-Authors: Christian Koos, Wim Bogaerts, Matthias Lauermann, Juerg Leuthold, Wolfgang Freude, Manfred Kohl, Larry R. Dalton, Anna Lena Giesecke, Argishti Melikyan, Sebastian KoeberAbstract:Silicon photonics offers tremendous potential for inexpensive high-yield photonic-electronic Integration. Besides conventional dielectric waveguides, plasmonic structures can also be efficiently realized on the silicon photonic platform, reducing device footprint by more than an order of magnitude. However, neither silicon nor metals exhibit appreciable second-order optical nonlinearities, thereby making efficient electro-optic modulators challenging to realize. These deficiencies can be overcome by the concepts of silicon-organic Hybrid (SOH) and plasmonic-organic Hybrid Integration, which combine SOI waveguides and plasmonic nanostructures with organic electro-optic cladding materials.

High-speed, low drive-voltage silicon-organic Hybrid modulator based on a binary-chromophore electro-optic material
Journal of Lightwave Technology, 2014Co-Authors: Sebastian Koeber, Markus Woessner, Dietmar Korn, Larry Dalton, Wim Bogaerts, Matthias Lauermann, Wolfgang Heni, Delwin L. Elder, Wolfgang FreudeAbstract:We report on the Hybrid Integration of silicon-on-insulator slot waveguides with organic electro-optic materials. We investigate and compare a polymer composite, a dendron-based material, and a binary-chromophore organic glass (BCOG). A record-high in-device electro-optic coefficient of 230 pm/V is found for the BCOG approach resulting in silicon-organic Hybrid Mach-Zehnder modulators that feature low \r\n $U_{\pi }L$\r\n -products of down to 0.52 Vmm and support data rates of up to 40 Gbit/s.

optical properties of highly nonlinear silicon organic Hybrid soh waveguide geometries
Optics Express, 2009Co-Authors: Thomas Vallaitis, Luca Alloatti, Michelle L Scimeca, Pieter Dumon, Roel Baets, Ivan Biaggio, C. Koos, Siegwart Bogatscher, Francois Diederich, Wolfgang FreudeAbstract:Geometry, nonlinearity, dispersion and two-photon absorption figure of merit of three basic silicon-organic Hybrid waveguide designs are compared. Four-wave mixing and heterodyne pump-probe measurements show that all designs achieve high nonlinearities. The fundamental limitation of two-photon absorption in silicon is overcome using silicon-organic Hybrid Integration, with a five-fold improvement for the figure of merit (FOM). The value of FOM = 2.19 measured for silicon-compatible nonlinear slot waveguides is the highest value published.

quantum photonics Hybrid Integration platform
Applied Physics Letters, 2015Co-Authors: E Murray, D J P Ellis, Thomas Meany, Frederik F Floether, J Griffiths, Gac Jones, Ian Farrer, D A RitchieAbstract:Fundamental to integrated photonic quantum computing is an on-chip method for routing and modulating quantum light emission. We demonstrate a Hybrid Integration platform consisting of arbitrarily designed waveguide circuits and single-photon sources. InAs quantum dots (QD) embedded in GaAs are bonded to a SiON waveguide chip such that the QD emission is coupled to the waveguide mode. The waveguides are SiON core embedded in a SiO2 cladding. A tuneable Mach Zehnder interferometer (MZI) modulates the emission between two output ports and can act as a path-encoded qubit preparation device. The single-photon nature of the emission was verified using the on-chip MZI as a beamsplitter in a Hanbury Brown and Twiss measurement.
