Complete 2π phase control by photonic crystal slabs
Optics Express, 2021 Photonic crystal slabs are the state of the art in the studies of the light confinement, optical wave modulating and guiding, as well as nonlinear optical response. Previous studies have shown abundant real-world implementations of photonic crystals in planar optics, metamaterials, sensors, and lasers.

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.

Automated optimization of photonic crystal slab cavities [PDF]
Scientific Reports, 2014 Thanks to their high quality factor, combined to the smallest modal volume, defect-cavities in photonic crystal slabs represent a promising, versatile tool for fundamental studies and applications in photonics. In paricular, the L3, H0, and H1 defects are the most popular and widespread cavity designs, due to their compactness, simplicity, and small ...

Effects of hydrostatic pressure on an L1 and L3 cavity of a photonic slab
Materials Research Express, 2020 In this work, we used the guided-mode expansion method to calculate the photonic band dispersion in two-dimensional photonic crystal slabs. The photonic lattice is hexagonal, composed of air holes with a circular cross-section.

Physical Review Research, 2022 We investigate the physics of photonic band structures of the moiré patterns that emerged when overlapping two unidimensional photonic crystal slabs with mismatched periods. The band structure of our system is a result of the interplay between intralayer

Photonic Bandgap Closure and Metamaterial Behavior in 1D Periodic Chains of High-Index Nanobricks
Photonics, 2022 It has been shown that the photonic bandgap of one-dimensional (1D) dielectric periodic thin films can vanish at the first Bragg condition for TM modes.

Realization of dual-band topological states in Su–Schrieffer–Heeger-like photonic crystal slabs
Results in Physics, 2023 We design the bilayer mirror-symmetric (I-shaped) photonic crystal slabs supporting dual-band topological edge states simultaneously, which is confirmed by the topological phases and localized field distributions.

Highly Reproducible, Bio‐Based Slab Photonic Crystals Grown by Diatoms
Advanced Science, 2020 Slab photonic crystals (PhCs) are photonic structures used in many modern optical technologies. Fabrication of these components is costly and usually involves eco‐unfriendly methods, requiring modern nanofabrication techniques and cleanroom facilities ...

Reconfigurable, Defect-Free, Ultrahigh-Q Photonic Crystal Microcavities for Sensing
Sensors, 2013 We propose a new approach for creating reconfigurable high-Q cavities in defect-free photonic crystal slabs (PCSs). The approach relies on selective air-hole infiltration in otherwise defect-free PCSs.
