Although perfectly matched layers (PMLs) have been widely used to truncate numerical
simulations of electromagnetism and other wave equations, we point out important cases in …

Through a new rigorous Bloch-mode formalism, we theoretically study the generation of
photons in single-row-defect photonic-crystal waveguides. In contrast with previous related …

We show that some previous proposals for perfectly matched layer (PML) absorbers in
anisotropic media or for waveguides at oblique incidence are not, in fact true PMLs; in …

We demonstrate on-chip, single-mode, waveguiding of light in air for a variety of 2D-3D
photonic band gap (PBG) heterostructures. These include square spiral, woodpile, slanted …

The manipulation of photons via artificially introduced line and point defects in photonic
crystals is becoming important for various scientific and engineering applications. Here, we …

We introduce a horn antenna in a three-dimensional layer-by-layer photonic crystal that
provides highly efficient transmission from a defect waveguide to free space. This device is …

We present an absorbing boundary condition for electromagnetic frequency domain
simulations of photonic crystals and metamaterials. This boundary condition can …

A complex‐coordinate method known under the guise of the perfectly matched layer (PML)
method for treating unbounded domains in computational electrodynamics is related to …

Although perfectly matched layers (PMLs) have been widely used to truncate numerical
simulations of electromagnetism and other wave equations, we point out important cases in …

The versatility of computational design as an alternative to design by nanofabrication has
made computers a reliable design tool in nanophotonics. Given that almost any 2d pattern …
