Fano resonance, known from atomic physics, has been employed for a wide variety of nanophotonic structures, such as quantum dots, photonic crystals (PCs), plasmonics, and metamaterials, and so on. [1] With modal dispersion engineering, Fano filters and reflectors can all be realized in single layer dielectric PC structures [2–4]. Suh et al. and Liu et al. reported earlier the optical Q-factors and...
We utilize the tight binding approximation within a light cone picture to relate the quality factor of CROWs with that of isolated cavity and to design CROWs with low intrinsic loss across the entire band.
Recently, the Fano resonance, known from atomic physics, has been employed for a wide variety of nanophotonic structures, such as quantum dots, photonic crystals (PCs), plasmonics, and metamaterials. [1, 2] With modal dispersion engineering, Fano filters and reflectors can all be realized in single-layer dielectric PC structures. [3–5] We report here ultra-compact surface-normal high-Q Fano resonance...
We introduce a novel design of an all-dielectric near-field biosensor based on guided resonances in photonic crystal slabs. We demonstrate biosensor fabrication using all-optical and e-beam lithography techniques, compatible with large scale replication.
