Optical Waveguides and Resonant Cavities
Description
Optical waveguides and resonant cavities offer highly valuable ways of manipulating and processing light over short distances. Low-loss propagation, efficient coupling to fibers, and ultracompact bends are paramount for creating low-cost photonics suitable for mass-markets. Novel forms of waveguiding are being further exploited: photonic crystal waveguides have the potential for low-loss guiding and exhibit slow light phenomena and surface plasmon waveguides are increasingly used for sensing and imaging applications. Moreover, optical single and coupled resonant cavities are important components in many communications and biosensing applications due to their high-Q and field confinement, increased sensitivity, and directional emission. These features can be valuably enhanced by coupling microresonators into so-called photonic molecules. Micro- and nanocavities are currently a major research focus in many leading organizations around the world, in particular their applications as optical switches and memory, wavelength converters, low-threshold lasers, and as single photon sources for quantum cryptography and quantum computing.
The main focus of this special issue will be on modeling, fabrication, and characterization methods that are employed to deal with the increased complexity of modern photonic waveguides and resonant cavities. Advances made in the area of novel materials and applications as well as review articles are also welcomed. The topics to be covered include, but are not limited to:
- Theory and modeling of waveguides and resonant cavities
- Photonic integrated circuits
- Nanophotonics
- Photonic crystals
- Nonlinear processes in optical waveguides and resonant single and coupled cavities
- Waveguide and cavity plasmons
- Optical filters
- Waveguide materials and fabrication techniques
- Characterization and testing of waveguides, resonant cavities, and materials
- Applications
