Focus on photonic crystal devices

25 Apr 2007

A series of invited articles in Journal of Physics D: Applied Physics offers a unique insight into some of the most recent advances in the application of photonic crystals (J. Phys. D 40 9).

The cluster of articles, edited by Professor Pallab K Bhattacharya of the University of Michigan, US, provides a glimpse into some of the most exciting opportunities that are being enabled by heterostructure photonic crystals (PCs) and their devices.

A range of topics is discussed, including the modeling of PC defect-mode cavities, the design and realization of ultrahigh Q heterostructure PC nanocavities, and the development of PC microcavity lasers. Two articles discuss the emerging subject of generating, controlling and propagating slow light in PCs, while another describes negative refraction in PCs.

In "Slow light engineering in photonic crystals", Toshihiko Baba and Daisuke Mori of Yokohama National University, Japan, discuss the potential of slow light devices and review some of the critical issues governing their design and application. And in "Slow light in photonic crystal waveguides", Thomas Krauss of the University of St. Andrews, UK, explains the physical principles behind the phenomenon of slow light in photonic crystal waveguides, as well as the practical limitations of these devices.

Meanwhile, Ekmel Ozbay and colleagues of Bilkent University, Turkey, describe negative refraction phenomena in two-dimensional PCs in "Negative refraction, subwavelength focusing and beam formation by photonic crystals". The researchers also describe a photonic-crystal flat lens that has the ability to focus electromagnetic waves and provide subwavelength resolution laterally.

All the cluster articles can be found in the latest issue of J. Phys. D and will be free to access until 19 July 2007.
