In this paper, we report a direct comparison between coupled resonator optical waveguides (CROWs) and photonic crystal waveguides (PhCWs), which have both been exploited as tunable delay lines. The two structures were fabricated on the same silicon-on-insulator (SOI) technological platform, with the same fabrication facilities and evaluated under the same signal bit-rate conditions. We compare the...
We investigate the nonlinear power transfer function generated through slow-light enhanced nonlinear absorption in silicon photonic crystal waveguides. Pulse regeneration and error reduction in a 10 Gbit/s data signal are observed for 10 MHz amplitude distortion.
Slow light photonic crystal waveguides can be dispersion-engineered with an unprecedented degree of control over the group index, propagation loss and injection efficiency. Ultrasmall optical switches and substantial enhancement of nonlinear effects are demonstrated.
We demonstrate enhanced nonlinear self-phase modulation through short silicon photonic crystal waveguides due to slow light using picosecond pulses. The measurements are supported by simulations, highlighting the simultaneous reinforcement of nonlinear absorption and free carriers.
We demonstrate reconfigurable microfluidic photonic crystal components in silicon-based membranes by select hole infiltration. We employ a diverse range of fluids and show the capability of filling a single hole. Systematic characterisations of the induced defects are presented.
Summary form only given. In the contribution, we show clear evidence that photonic crystals (PC) can be used in ultrasmall integrated optics to cascade two elements, in this case a cavity and a waveguide. We use as a basis PC a triangular array of holes of period a=220-260 nm etched through an AlGaAs planar waveguide, in which we define a hexagonal cavity of side h=7a (H7 cavity), and a guide with...
Summary form only given. Using the transfer matrix method the transmission co-efficient was determined for periodic defect states in a hexagonal lattice. The hexagonal lattice is created by removing cylindrical air holes from a background dielectric media with a dielectric constant of 7.9. This value was chosen to represent a half-wavelength thick GaAs waveguide from which the cylindrical holes were...
