Silicon microring resonators
An overview is presented of the current state-of-the-art in silicon nanophotonic ring resonators. Basic theory of ring resonators is discussed, and applied to the peculiarities of submicron siliconExpand
Grating Couplers for Coupling between Optical Fibers and Nanophotonic Waveguides
Nanophotonic waveguides and components are promising for use in the large-scale integration of photonic circuits. Coupling light between nanophotonic waveguides and a single-mode fiber is anExpand
Nanophotonic waveguides in silicon-on-insulator fabricated with CMOS technology
High-index-contrast, wavelength-scale structures are key to ultracompact integration of photonic integrated circuits. The fabrication of these nanophotonic structures in silicon-on-insulator usingExpand
All-optical high-speed signal processing with silicon–organic hybrid slot waveguides
Integrated optical circuits based on silicon-on-insulator technology are likely to become the mainstay of the photonics industry. Over recent years an impressive range of silicon-on-insulator devicesExpand
Low-loss SOI photonic wires and ring resonators fabricated with deep UV lithography
We demonstrate single-mode photonic wires in silicon-on-insulator with propagation loss as low as 2.4 dB/cm, fabricated with deep ultraviolet lithography and dry etching. We have also made compactExpand
Compact Wavelength-Selective Functions in Silicon-on-Insulator Photonic Wires
We present a number of compact wavelength-selective elements implemented in silicon-on-insulator (SOI) photonic wires. These include arrayed waveguide gratings (AWGs), Mach-Zehnder lattice filtersExpand
An out-of-plane grating coupler for efficient butt-coupling between compact planar waveguides and single-mode fibers
We have designed and fabricated an out-of-plane coupler for butt-coupling from fiber to compact planar waveguides. The coupler is based on a short second-order grating or photonic crystal, etched inExpand
Low-loss, low-cross-talk crossings for silicon-on-insulator nanophotonic waveguides.
We present compact crossings for silicon-on-insulator photonic wires. The waveguides are broadened using a 3 microm parabolic taper in each arm. By locally applying a lower index contrast using aExpand
Silicon-on-Insulator Spectral Filters Fabricated With CMOS Technology
We give an overview of recent progress in passive spectral filters and demultiplexers based on silicon-on-insulator photonic wire waveguides: ring resonators, interferometers, arrayed waveguideExpand
Real-space observation of ultraslow light in photonic crystal waveguides.
We show the real-space observation of fast and slow pulses propagating inside a photonic crystal waveguide by time-resolved near-field scanning optical microscopy. Local phase and group velocities ofExpand
