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 …

Topology optimization is used to design a planar photonic crystal waveguide component
resulting in significantly enhanced functionality. Exceptional transmission through a photonic …

Topology optimization is a promising method for systematic design of optical devices. As an
example, we demonstrate how the method can be used to design a 90 bend in a two …

The great interest in photonic crystals and their applications in the last 15 years is being
expressed in the publishing of a large number of monographs, collections, textbooks and …

Topology optimization has been used to design a 60° bend in a single-mode planar
photonic crystal waveguide. The design has been realized in a silicon-on-insulator material …

We present a new technique for the design of transformation-optics devices based on large-
scale optimization to achieve the optimal effective isotropic dielectric materials within …

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× …

This review paper summarizes our previous findings regarding propagation characteristics
of band-gap temporal solitons in photonic crystal waveguides with Kerr-type nonlinearity …
