Analysis of guided resonances in photonic crystal slabs
We present a three-dimensional analysis of guided resonances in photonic crystal slab structures that leads to a new understanding of the complex spectral properties of such systems. Specifically, we… Expand

We present a theory of the Fano resonance for optical resonators, based on a temporal coupled-mode formalism. This theory is applicable to the general scheme of a single optical resonance coupled… Expand
Guided modes in photonic crystal slabs
We analyze the properties of two-dimensionally periodic dielectric structures that have a band gap for propagation in a plane and that use index guiding to confine light in the third dimension. Such… Expand
Coupling of modes analysis of resonant channel add-drop filters
The operation principle of resonant channel add-drop filters based on degenerate symmetric and antisymmetric standing-wave modes has been described elsewhere using group theoretical arguments. In… Expand
Passive radiative cooling below ambient air temperature under direct sunlight
Cooling is a significant end-use of energy globally and a major driver of peak electricity demand. Air conditioning, for example, accounts for nearly fifteen per cent of the primary energy used by… Expand
Photonic crystals: putting a new twist on light
Photonic crystals are materials patterned with a periodicity in dielectric constant, which can create a range of 'forbidden' frequencies called a photonic bandgap. Photons with energies lying in the… Expand
Optical absorption enhancement in amorphous silicon nanowire and nanocone arrays.
Hydrogenated amorphous Si (a-Si:H) is an important solar cell material. Here we demonstrate the fabrication of a-Si:H nanowires (NWs) and nanocones (NCs), using an easily scalable and IC-compatible… Expand
S4 : A free electromagnetic solver for layered periodic structures
Abstract We describe S 4 , a free implementation of the Fourier modal method (FMM), which has also been commonly referred to as rigorous coupled wave analysis (RCWA), for simulating electromagnetic propagation through 3D structures with 2D periodicity. Expand
Complete optical isolation created by indirect interband photonic transitions
Achieving on-chip optical signal isolation is a fundamental difficulty in integrated photonics . The need to overcome this difficulty, moreover, is becoming increasingly urgent, especially with… Expand
Coherent photon transport from spontaneous emission in one-dimensional waveguides.
A two-level system coupled to a one-dimensional continuum is investigated. By using a real-space model Hamiltonian, we show that spontaneous emission can coherently interfere with the continuum modes… Expand
