“…These were calculated using the reduced Bloch mode expansion technique [57] based on the plane wave expansion method [58,59]. IFCs are dispersion surfaces in kspace that characterize the magnitude of the wave vector as a function of the direction of a Bloch wave propagating through a uniform infinite lattice.…”

Abstract-In this work, results are given for controlling waves arbitrarily inside a lattice with spatially variant self-collimation. To demonstrate the concept, an unguided beam was made to flow around a 90 • bend without scattering due to the bend or the spatial variance. Control of the field was achieved by spatially varying the orientation of the unit cells throughout a self-collimating photonic crystal, but in a manner that almost completely eliminated deformations to the size and shape of the unit cells. The device was all-dielectric, monolithic, and made from an ordinary dielectric with low relative permittivity (ε r = 2.45). It was manufactured by fused deposition modeling, a form of 3D printing, and its performance confirmed experimentally at around 15 GHz.

Sandwich-structured TiO₂ inverse opal circulates slow photons for tremendous improvement in solar energy conversion efficiency

To cite this version:Photon management has enabled a true revolution in the development of high-performance semiconductor materials and devices. Harnessing the highest amount of energy from photon relies on an ability to design and fashion structures to trap the light for the longer time inside the device for more electron excitation. The light harvesting efficiency in many thin-film optoelectronic devices is limited due to low photon absorbance. Here we demonstrate for the first time that slow photon circulation in sandwich-structured photonic crystals with two stopbands fine tuned are ideally suited to enhance and spectrally engineer light absorption. The sandwich-structured TiO 2 inverse opal possesses two stopbands, whose blue or red edge is respectively tuned to overlap with TiO 2 electronic excitation energy, thereby circulating the slow photons in the middle layer and enhancing light scattering at layer interfaces. This concept, together with the significantly increased control over photon management opens up tremendous opportunities for the realization of a wide range of highperformance, optoelectronic devices, and photochemical reactions.

Abstract-The near-field surrounding devices can be arbitrarily sculpted if they are embedded in a spatially variant anisotropic metamaterial (SVAM). Our SVAMs are low loss because they do not contain metals and are extraordinarily broadband, working from DC up to a cutoff. In the present work, a microstrip transmission line was isolated from a metal object placed in close proximity by embedding it in a SVAM so that the field avoided the object. Our paper begins by outlining a simple model for studying transmission lines embedded in SVAMs. We then present our design and experimental results to confirm the concept.
