    • Silicon-on-insulator (SOI) nanowires give a very promising way to realize ultrasmall photonic integrated devices because of the ability for ultrasharp bending as well as the CMOS compatibility. As a typical integrated-type (de) multiplexer, ultrasmall arrayed-waveguide gratings (AWG) are very attractive for many applications. We have developed several types of ultrasmall SOI-nanowire AWG with novel layouts. SOI nanowires also give a good platform for optical sensing with high sensitivity because of the enhanced evanescent field. We have developed SOI-nanowire-based optical sensors by using MZI (Mech-Zehnder interferometer)-coupled microrings and cascaded rings. We also note that the size of an SOI nanowire is still limited to the order of wavelength in each direction. In contrast, surface plasmon (SP) waveguides could provide a nano-scale waveguiding and confinement of light. However, the conventional nano-scale SP waveguides are usually quite lossy. We have proposed two types of novel hybrid plasmonic waveguides to achieve nano-scale optical confinement and low-loss light propagation. Due to the ultra-high optical confinement, sub-mu m-2 hybrid plasmonic devices (e. g., power splitters) are presented. It is also shown that hybrid plasmonic waveguide enables sub-mu m bending and thus sub-mu m resonator has been also demonstrated. The hybrid plasmonic waveguides offer a way to transfer both photonic and electronic signals along the same circuit, which is attractive for active components, e. g., tunable filters and optical modulators.

  • 2012

    • Hybrid plasmonic waveguides and directional couplers have been experimentally demonstrated. Using a direct measurement method, the propagation loss of a 170 nm wide waveguide is measured to be 0.08 dB/mu m at 1550 nm when the thickness of low-index region is 56 nm. Ultra-compact directional couplers based on such hybrid plasmonic waveguides are demonstrated with gaps of 140 nm, 185 nm, 235 nm, and 290 nm. The corresponding coupling lengths measured are 1.55 mu m, 2.2 mu m, 3.2 mu m, and 4.8 mu m, respectively, which are in very good agreement with the simulations. These ultra-compact devices can be potentially used in future ultra-dense photonic integrated circuits.

  • Ultracompact polarization beam splitter based on a dielectric-hybrid plasmonic-dielectric coupler
  • 2012
  • Ingår i: Optics Letters. - 0146-9592 .- 1539-4794. ; 37:16, s. 3372-3374
  • Tidskriftsartikel (refereegranskat)abstract
    • An ultracompact polarization beam splitter (PBS) based on a dielectric-hybrid plasmonic-dielectric coupler is proposed. The device utilizes the polarization-dependent nature of hybrid plasmonic waveguides. By choosing proper waveguide parameters, a 2 x 5.1 mu m(2) PBS (including S-bends) with extinction ratios over 15 dB and insertion losses below 1.5 dB in the full C-band should be achievable. The effect of fabrication errors is also investigated.

  • Ingår i: Optoelectronic Integrated Circuits XIV. - : SPIE - International Society for Optical Engineering. - 9780819489081 ; , s. 826506-
  • Konferensbidrag (refereegranskat)abstract
    • Silicon photonics is an emerging technology offering novel solutions in different areas requiring highly integrated communication systems for optical networking, sensing, bio-applications and computer interconnects. Silicon photonicsbased communication has many advantages over electric wires for multiprocessor and multicore macro-chip architectures including high bandwidth data transmission, high speed and low power consumption. Following the INTEL's concept to "siliconize" photonics, silicon device technologies should be able to solve the fabrication problems for six main building blocks for realization of optical interconnects: light generation, guiding of light including wavelength selectivity, light modulation for signal encoding, detection, low cost assembly including optical connecting of the devices to the real world and finally the electronic control systems.
