Electromagnetic waves follow linear paths in homogenous index media, with the exception of band edges. In this study, we introduced spatially distorted photonic crystals (D-PCs) that are capable of beam-steering light waves, even when a homogeneous refractive index is maintained. We analyzed their equifrequency contours to investigate the correspondence between the direction of distortion and the direction of the group velocity vector in the D-PC. Thereafter, we experimentally verified the beam… 


Theory of light propagation in strongly modulated photonic crystals: Refractionlike behavior in the vicinity of the photonic band gap
Although light propagation in weakly modulated photonic crystals is basically similar to propagation in a diffraction grating in which conventional refractive index loses its meaning, we demonstrate
Superprism Phenomena in Photonic Crystals
Extraordinary angle-sensitive light propagation, which we call a superprism phenomenon , was demonstrated at optical wavelength in photonic crystals with three-dimensional-periodic structure
Photonic crystal light deflection devices using the superprism effect
The superprism effect allows wide-angle deflection of the light beam in a photonic crystal (PC) by a slight change of the wavelength or the incident angle. In this paper, we discuss such light
Polarization control by modulated photonic-crystal lasers.
For one-directional position modulation, it is shown that the polarization of output beams is perpendicular to the direction of modulation and that circularly polarized beams are obtained.
Simultaneous Inhibition and Redistribution of Spontaneous Light Emission in Photonic Crystals
This work demonstrates both the “inhibition” and “redistribution” of spontaneous light emission by using two-dimensional photonic crystals, in which the refractive index is changed two-dimensionally.
Experimental Verification of a Negative Index of Refraction
These experiments directly confirm the predictions of Maxwell's equations that n is given by the negative square root ofɛ·μ for the frequencies where both the permittivity and the permeability are negative.
Photonic-Crystal Surface-Emitting Lasers: Review and Introduction of Modulated-Photonic Crystals
Photonic-crystal surface-emitting lasers (PCSELs) have attracted much attention for their unrivaled capabilities, such as broad area, coherent resonance, tailored beam patterns, and beam steering. In
Efficient light bending with isotropic metamaterial Huygens' surfaces.
A broadband Huygens' surface that efficiently refracts normally incident light at the telecommunication wavelength of 1.5 μm is reported.
Half-Maxwell fisheye lens with photonic crystal waveguide for the integration of terahertz optics.
Experiments indicate that a slab-mode beam is launched with ∼86% efficiency, over a broad 3 dB bandwidth from ∼260 to ∼390 GHz, although these reported values are approximate due to obfuscation by variation that arises from reflections within the device.
Strain-induced pseudomagnetic field and photonic Landau levels in dielectric structures
Magnetic effects are fundamentally weak at optical frequencies. Now, by applying inhomogeneous strain in photonic band structures of a honeycomb lattice of waveguides, scientists show experimentally
