Advancing the performance of one-dimensional photonic crystal/photonic wire micro-cavities in silicon-on-insulator [PDF]
, 2008 We present new results that demonstrate advances in the performance achievable in photonic crystal/photonic wire micro-cavities. In one example, a quality-factor value as high as 147,000 has been achieved experimentally at a useful transmission ...

Resonance and Bound States in Photonic Crystal Slabs [PDF]
SIAM Journal on Applied Mathematics, 2003 Summary: Using boundary-integral projections for time-harmonic electromagnetic (EM) fields, and their numerical implementation, we analyze EM resonance in slabs of two-phase dielectric photonic crystal materials. We characterize resonant frequencies by a complex Floquet-Bloch dispersion relation \(\omega = W(\beta)\) defined by the existence of a ...
