The behavior of two coupled photonic crystal membrane cavities with quantum dots separated by different number of holes is investigated. The measured spectral splitting with increased coupling is verified by 3D calculations and discussed.
We report first observations of deterministic phase- and resonance-controlled all-optical analogue to electromagnetically induced transparency in coherently-coupled silicon photonic crystal nanocavities through thermo-optic tuning method, for realization of all-optical dynamical storage of light.
We demonstrated 6-THz wavelength conversion of a 10 Gbit/s DPSK signal via four-wave-mixing in a silicon coupled resonator optical waveguide. The device provides 16 dB enhancement of the conversion efficiency with negligible phase information distortion.
We show that trench defect in a photonic crystal slab leads to efficient wave-guiding. Based on trench-waveguide geometry, slow-light devices and coupled-cavity micro-resonator arrays can be fabricated with scalable (holographic) photolithography avoiding electron-beam lithography.
Splitting of mode wavelength and loss are observed in coupled photonic-crystal cavities. The characteristics of loss splitting are shown to have important impact on the optical energy transfer between such coupled resonators.
Compact elliptic optical filter architectures based on arrays of parallel-cascaded microring doublets are proposed. These devices can realize general filter transfer functions with imaginary transmission zeros using only synchronously-tuned microrings with non-negative couplings.
We study coupling between surface plasmons in metal-hole arrays. We observe avoided crossings in the measured transmission spectra for metal-hole arrays with a dielectric pillar in each hole and for arrays in index matching liquid.
We observe experimentally all-optical analogue to electromagnetically induced transparency with silicon photonic crystal nanocavities having high intrinsic quality factor and small modal volume. This phenomenon is analyzed through coupled-mode formalism and three-dimensional finite-difference time-domain method.
The surface plasmon coupling between gold nanoparticles in a periodic array is theoretically modeled. The calculated dispersion relation and loss properties of an array of chains at air/glass interface agree well with FDTD simulation results.

Cascaded over- and under-coupled resonators (COUR) result in slow light followed by fast light. COUR can be used as a notch filter and phase modulator that overcomes the trade-offs of extinction-ratio-group-delay and sensitivity-bandwidth.
