Photonic band structure theory: assessment and perspectives

An attempt is made to provide an assessment on the current state of photonic bandstructure theory, a field of research which is at the heart of rapid progress in photonic crystal research. First, different approaches to calculating photonic bandstructures as well as the optical properties of defect structures in photonic crystals are reviewed. Several highlights and applications of photonic bandstructure theory are presented that help to illustrate the tremendous progress the field has seen. Finally, perspectives of photonic bandstructure theory are briefly discussed and an attempt is made to identify possible future developments. To cite this article: K. Busch, C. R.
