Topology optimization is a computational tool that can be used for the systematic design of
photonic crystals, waveguides, resonators, filters and plasmonics. The method was originally …

Periodic nanostructures in photonics facilitate a far-reaching control of light propagation and
light–matter interaction. This article reviews the current status of this subject, including both …

Nanophotonics is where photonics merges with nanoscience and nanotechnology, and
where spatial confinement considerably modifies light propagation and light-matter …

The photonic nanojet (PNJ) is a narrow high-energy beam that was originally found on the
back side of all-dielectric spherical structures. It is a unique type of energy concentration …

Nano-photonic technologies of GaAs-based two-dimensional photonic crystal (2DPC) slab
waveguides (WGs) and InAs-based quantum dots (QDs) are reviewed for a symmetrical …

We present an efficient parallel topology optimization framework for design of large scale 3D
nanophotonic devices. The code shows excellent scalability and is demonstrated for …

We designed, fabricated, and characterized broadband, efficient, all-dielectric metamaterial-
waveguide bends (MWBs) that redirect light by 180 deg. The footprint of each MWB is 3 μm× …

We propose a design method for optical waveguide devices based on topology optimization
with alternative expression of refractive index distribution. In our approach, a refractive index …

In this article, we design a low-loss, high-bandwidth Z-bend photonic silicon crystal
waveguide bending in a triangular lattice through topology optimization. Based on the …

This paper explores optimal topologies yielding large band gap shifts in one-and two-
dimensional nonlinear periodic materials. The presence of a nonlinearity in a periodic …
