Ultra-compact, flat-top demultiplexer using anti-reflection contra-directional couplers for CWDM networks on siliconWei Shi
Department of Electrical and Computer Engineering, University of British Columbia, Vancouver, BC, Canada
Opt Express 21:6733-8. 2013..Using such filter components, we demonstrate a 4-channel, coarse-WDM demultiplexer with flat passbands of up to 13 nm and an ultra-compact size of 1.2 × 10(-3) mm(2)...
Silicon photonic grating-assisted, contra-directional couplersWei Shi
Department of Electrical and Computer Engineering, University of British Columbia, Vancouver, BC, Canada
Opt Express 21:3633-50. 2013..These contra-DC devices enable on-chip integration of Bragg-grating-defined functions without using circulators and have great potential for applications such as wavelength-division multiplexing networks and optical signal processing...
Ultra-compact, high-Q silicon microdisk reflectorsWei Shi
Department of Electrical and Computer Engineering, The University of British Columbia, Vancouver, BC, Canada
Opt Express 20:21840-6. 2012..The coupling between a microdisk and a waveguide is numerically investigated. We further propose a multichannel sensing system using cascaded microdisk reflectors...
Contradirectional couplers in silicon-on-insulator rib waveguidesW Shi
Department of Electrical and Computer Engineering, The University of British Columbia, Vancouver, BC, Canada
Opt Lett 36:3999-4001. 2011..The simulation using coupled-mode theory and mode-profile calculations shows good agreement with experiment. A narrow bandwidth of 0.35 nm and a low loss of less than 1 dB have been achieved experimentally...
Design and characterization of microring reflectors with a waveguide crossingWei Shi
Department of Electrical and Computer Engineering, University of British Columbia, Vancouver, British Columbia, Canada
Opt Lett 35:2901-3. 2010..The measurement shows an extinction ratio greater than 25 dB and a resonance-wavelength temperature dependence of 0.09 nm/K...
Narrow-band waveguide Bragg gratings on SOI wafers with CMOS-compatible fabrication processXu Wang
Department of Electrical and Computer Engineering, University of British Columbia Vancouver, BC, V6T 1Z4, Canada
Opt Express 20:15547-58. 2012..We also present the die-to-die nonuniformity for the grating devices on the wafer, and our analysis shows that the Bragg wavelength deviation is mainly caused by the wafer thickness variation...
Mosaic acquisition and processing for optical-resolution photoacoustic microscopyPeng Shao
University of Alberta, Department of Electrical and Computer Engineering, Edmonton T6G2V4, Canada
J Biomed Opt 17:080503-1. 2012..After all imaging locations are covered, a large panoramic scene is generated by stitching the mosaic patches together. Our proposed system is proven to be at least 20 times faster than previous reported OR-PAM systems...
Integrated micro-endoscopy system for simultaneous fluorescence and optical-resolution photoacoustic imagingPeng Shao
University of Alberta, Department of Electrical and Computer Engineering, Edmonton, Alberta, T6G 2V4, Canada
J Biomed Opt 17:076024. 2012..Therefore, the system has the potential to serve as a virtual biopsy technique, helping visualize angiogenesis and the effects of anti-cancer drugs on both cells and the microcirculation, as well as aid in the study of other diseases...
In vivo dynamic process imaging using real-time optical-resolution photoacoustic microscopyWei Shi
University of Alberta, Department of Electrical and Computer Engineering, Edmonton, Alberta, Canada, T6G 2V4
J Biomed Opt 18:26001. 2013....
Real-time handheld optical-resolution photoacoustic microscopyParsin Hajireza
Department of Electrical and Computer Engineering, University of Alberta, Edmonton, Alberta T6G 2V, Canada
Opt Express 19:20097-102. 2011..The compact, flexible nature of the proposed design and the small footprint of the apparatus increase the usability of OR-PAM for potential clinical applications such as in dermatology...
