Photonic Crystal Devices in Silicon Photonics
Proceedings of the IEEE, 2018In this paper, we review the history of 2-D photonic crystal slabs with a focus on point-defect cavities that can simultaneously realize ultrasmall modal volumes and ultrahigh quality factors. An important design concept to suppress radiation loss is introduced: the envelope of the cavity mode field should have no abrupt changes and should ideally ...

We present a concept of graded photonic crystals used to enhance the control of light propagation. Gradual modifications of the lattice periodicity make it possible to bend the light at the micrometer scale. This effect is tailored by parametric studies of the isofrequency curves. As a demonstration, we propose a two-dimensional graded photonic crystal

Photonic crystal fibers guide light by corralling it within a periodic array of microscopic air holes that run along the entire fiber length. Largely through their ability to overcome the limitations of conventional fiber optics—for example, by permitting low-loss guidance of light in a hollow core—these fibers are proving to have a multitude of ...

Impedance of photonic crystals and photonic crystal waveguides
Applied Physics Letters, 2004We develop and demonstrate the concept of impedance for a photonic crystal by generalizing the transverse wave impedance of conventional waveguides. The impedance involves a ratio of transverse fields and power flux. The calculated impedance for a two-dimensional photonic crystal is very well defined using the transfer matrix method.

Photonic crystal fibers exhibit physical features, from various angles, more versatile, intriguing and promising than those pertaining to the conventional optical fibers. Their cross-section can be optimized to obtain single mode operation on a wide wavelength range, soliton propagation, regeneration application, controllable group velocity dispersion.

Photonic crystal fibres have wavelength-scale morphological microstructure running down their length. This structure enables light to be controlled within the fibre in ways not previously possible or even imaginable. Our understanding of what an optical fibre is and what it does is changing because of the development of this new technology, and a broad

SPIE Proceedings, 2006Recent important advances in subwavelength nanostructures offer extraordinary control over the properties of light. We can now manipulate the propagation, storage, and generation of light, as well as practically prescribe its matter interaction properties based on first-principles.
