Waveguides, bends and Y-junctions with improved transmission and bandwidth in hexagon-type SOI photonic crystal slabs [PDF]
, 2005 This paper presents novel ways of implementing waveguide components in photonic crystal slabs based on silicon-on-insulator (SOI). The integration platform we consider consists of hexa¬gonal holes arranged in a triangular lattice (‘hexagon-type’ photonic

Reconfigurable microfluidic photonic crystal slab cavities
Optics Express, 2008 We demonstrate the spectral and spatial reconfigurability of photonic crystal double-heterostructure cavities in silicon by microfluidic infiltration of selected air holes. The lengths of the microfluidic cavities are changed by adjusting the region of infiltrated holes in steps of several microns.

High-Q Defect-Free 2D Photonic Crystal Cavity from Random Localised Disorder
Crystals, 2014 We propose a high-Q photonic crystal cavity formed by introducing random disorder to the central region of an otherwise defect-free photonic crystal slab (PhC).

Design of waveguides, bends and splitters in photonic crystal slabs with hexagonal holes in a triangular lattice [PDF]
, 2005 Waveguides in photonic crystal slabs (PCS) can be obtained by omitting a row of holes (W1-waveguides). In general the propagation properties in such waveguides suffer from the unavoidable periodic sidewall corrugation caused by the remaining parts of the

Deeply subwavelength phonon-polaritonic crystal made of a van der Waals material
Nature Communications, 2019 Photonic crystals can steer, shape, and sculpture the flow of photons. Here, the author fabricate a deep-subwavelength photonic crystal slab that supports ultra-confined phonon polaritons, by patterning a nanoscale hole array in h-BN.

Two-dimensionally confined topological edge states in photonic crystals
New Journal of Physics, 2016 We present an all-dielectric photonic crystal structure that supports two-dimensionally confined helical topological edge states. The topological properties of the system are controlled by the crystal parameters.

High coupling efficiency to a low dispersion slow light-supporting photonic crystal waveguide [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 In this paper, we design a waveguide on photonic crystal slab for propagation of low-dispersion slow light. By shifting the air holes adjacent to the waveguide, we obtain a photonic crystal waveguide with a group index of 25 in 25 nm bandwidth which ...

Photonic band gaps and defect modes of polymer photonic crystal slabs [PDF]
, 2005 We show from the photonic band calculation and the finite difference time domain simulation that polymer photonic crystal slabs with a triangular array of air holes can exhibit complete photonic band gaps for transverse electric-like modes. A line defect
