A new class of composite materials has emerged which provides a means to control and
manipulate light. These materials, known as photonic crystals, are periodic arrays of …

Nanotechnology, science, and engineering spearhead the 21st century revolution that is
leading to fundamental breakthroughs in the way materials, devices, and systems are …

A comprehensive review considering recent advances in self‐collimation and its
applications in optical integration is covered in the current article. Self‐collimation is …

Although electrons and photons are intrinsically different, importing useful concepts in optics
to electronics performing similar functions has been actively pursued over the last two …

We present finite-difference time-domain studies for self-collimated beams in photonic
crystal structures. Using a pulse propagation technique that eliminates the interference from …

We perform full 3D topology optimization (in which “every voxel” of the unit cell is a degree of
freedom) of photonic-crystal structures in order to find optimal omnidirectional band gaps for …

Diffraction, a fundamental process in wave physics, leads to spreading of the optical beams
as they propagate. However, new photonic crystal (PhC) meta-materials can be nano …

We report a tunable nanophotonic device concept based on flexible photonic crystal, which
is comprised of a periodic array of high-index dielectric material and a low-index flexible …

In this paper, we report on the development of the self-collimation phenomenon in photonic
crystal structures for integrated optics applications. In addition, detailed numerical analysis …

Here, we demonstrate a compact photonic crystal wavelength demultiplexing device based
on a diffraction compensation scheme with two orders of magnitude performance …
