Using Plasmonic Photonic Crystals to Produce Highly Efficient Thermophotovoltaic Solar Cells

Highly Directive Radiation and Negative Refraction Using Photonic Crystals

In this article, we present an experimental and numerical study of certain optical properties of twodimensional dielectric photonic crystals (PCs). By modifying the band structure of a two-dimensional photonic crystal through its crystal parameters, we show how it is possible to confine the angular distribution of radiation from an embedded omnidirectional source. We then demonstrate that the a...

Silicon Photonic Crystals Towards Optical Integration

Fabrication of 2-D photonic crystals using azo polymers

In this paper, we have reported the fabrication of two-dimensional photonic crystals, using a direct writing method in azo polymers. Periodic structures have been fabricated using the interference patterns of two coherent laser beams. The frequency response of the initial one-dimensional structure shows an attenuation of 19.3dB at 1554nm. The twodimensional structure shows 8.3dB and 11.3dB of a...

Highly directional emission from photonic crystals with a wide bandwidth

The authors numerically and experimentally demonstrated highly directional emission from photonic crystals. This was achieved by first splitting the incident electromagnetic wave into multiple beams using photonic crystal waveguide structures. The beams were then emitted out of the surface of a photonic crystal with the same phase, which resulted in a highly directional radiation pattern. The m...
