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 ...

Polarization mixing, bound states in a continuum, and exciton-polaritons in photonic crystal slabs by a guided-mode expansion approach [PDF]
EPJ Web of ConferencesPhotonic crystal (PhC) slabs, or patterned multilayer waveguides, are known to support truly guided modes with no losses, as well as quasi-guided modes that lie in the continuum of far-field radiation.

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.

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.

Sensitivity enhancement in photonic crystal slab biosensors
Optics Express, 2010 Refractive index sensitivity of guided resonances in photonic crystal slabs is analyzed. We show that modal properties of guided resonances strongly affect spectral sensitivity and quality factors, resulting in substantial enhancement of refractive index sensitivity.

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.

Photonic bands and gap maps in a photonic crystal slab [PDF]
IEEE Journal of Quantum Electronics, 2002 The photonic bands of a two-dimensional (2-D) lattice patterned in a planar waveguide are calculated by expanding the magnetic field on the basis of waveguide modes. The method yields both the truly guided modes of the structure as well as the quasi-guided modes (or guided resonances) which lie above the light line in the first Brillouin zone ...
