  • Design and fabrication of compact etched diffraction grating demultiplexers based on alpha-Si nanowire technology
  • 2008
  • Ingår i: Electronics Letters. - : Institution of Engineering and Technology (IET). - 0013-5194 .- 1350-911X. ; 44:13, s. 816-818
  • Tidskriftsartikel (refereegranskat)abstract
    • alpha-Silicon nanowire waveguides and related techniques are studied. An ultra-compact etched diffraction grating demultiplexer with 10 nm spacing is fabricated and characterised. The dimension of the device is around half a millimetre, which is one to two orders of magnitude smaller than conventional silica based devices.

  • Liver X receptor agonist downregulates hepatic apoM expression in vivo and in vitro
  • 2008
  • Ingår i: Biochemical and Biophysical Research Communications. - : Elsevier BV. - 1090-2104 .- 0006-291X. ; 371:1, s. 114-117
  • Tidskriftsartikel (refereegranskat)abstract
    • It has been demonstrated that apolipoprotein M (apoM), a recently discovered HDL apolipoprotein, has antiatherosclerotic properties, which may be mediated by the enhancement of reversed cholesterol transportation and/or hepatic cholesterol catabolism. The detailed mechanisms are unknown yet. Liver X receptor (LXR) belongs to the nuclear receptor superfamily and is a ligand-activated transcription factor involved in the regulation of lipid metabolism and inflammation. Activation of LXR in the cell cultures results in an enhancement of cholesterol efflux to apoAl. In the present study, we investigated effects of the LXR agonist, T0901317 on hepatic apoM expression in vivo and in vitro. Serum apoM levels in mice given T0901317 at 10 mg or 100 mg/kg for 7 days were reduced by 12-17% (P < 0.05). In HepG2 cell cultures, apoM mRNA levels were significantly lower in presence of 25 mu M T0901317 (37.1%) than in control cells (P < 0.001). A similar reduction was found by the addition of 9-cis retinoic acid (RA). Twenty-five micromolar T0901317 together with 100 nM RA decreased apoM mRNA expression by 65% (P < 0.001). Thus, the LXR agonist T0901317 significantly downregulates apoM mRNA expression in vivo and in vitro, which indicates that apoM is another novel target gene regulated by the LXR. The combination of RA and T0901317 showed additive effects, which suggests that apoM expression can be modulated by LXR/RXR pathway.

  • A hybrid modeling for the theoretical analysis of reflections in a multimode-interference coupler based on silicon-on-insulator nanowires
  • 2008
  • Ingår i: Optics Communications. - : Elsevier BV. - 0030-4018 .- 1873-0310. ; 281:11, s. 3099-3104
  • Tidskriftsartikel (refereegranskat)abstract
    • A hybrid method combining the three-dimensional (3D) beam propagation method (BPM) and a 3D finite-difference time-domain (FDTD) method is presented for the simulation of multimode-interference (MMI) couplers based on silicon-on-insulator (SOI) nanowires. This hybrid method makes it possible to have a robust analysis for the reflection properties while avoiding a time-consumed computation with a simplex 3D-FDTD simulation. The reflected power is sensitive to both the length and the width of the MMI coupler and thus one should choose the optimal values for good self-imaging. Furthermore, the reflection could be reduced by introducing tapers between the MMI section and the access waveguides.

  • Konferensbidrag (refereegranskat)abstract
    • We present fabrication and measurement results of an ultracompact silicon-on-insulator-based echelle-grating triplexer, which uses different diffraction orders to cover a large spectral range from 1.3 mu m to 1.5 mu m, with a footprint of 150 mu m x 200 mu m.

  • Design of a polarization-insensitive echelle grating demultiplexer based on silicon nanophotonic wires
  • 2008
  • Ingår i: IEEE Photonics Technology Letters. - : Institute of Electrical and Electronics Engineers (IEEE). - 1041-1135 .- 1941-0174. ; 20:9-12, s. 860-862
  • Tidskriftsartikel (refereegranskat)abstract
    • A polarization-insensitive design of an echelle grating (or etched diffraction grating) demultiplexer based on silicon nanowires is proposed in the present letter, by introducing a polarization compensation area in its free propagation region. The polarization-dependent wavelength shift of the present device has been compensated at the whole spectral range. For a design with nine channels and 10-nm channel spacing, when the wavelength shift at the central channel 1550 nm is. completely compensated, the wavelength shifts of the two edge channels are only 0.14 and 0.15 nm, which are acceptable.

  • Total internal reflection type echelle grating demultiplexer based on amorphous silicon nanowire platform
  • 2008
  • Ingår i: Proceedings of SPIE - The International Society for Optical Engineering. - Hangzhou : SPIE.
  • Konferensbidrag (refereegranskat)abstract
    • In this paper we present measurement results of an ultracompact echelle-grating demultiplexer based on silicon-on-insulator nanowire platform, in which we introduced a total internal reflection design of the grating facets to improve the diffraction efficiency. An average increase of the diffraction efficiency with 3.7dB is observed for the 3 channels compared to a normal design.
