A model system for two-dimensional and three-dimensional photonic crystals : macroporous silicon : Special issue on photonic bandgaps
Jörg Schilling,Ralf B. Wehrspohn,A. Birner,Frank Müller,Reinald Hillebrand,U. Gösele,S. W. Leonard,J. P. Mondia,F. Genereux,H. M. van Driel,P. Kramper,Vahid Sandoghdar,Kurt Busch +12 more
TL;DR: In this paper, a review of the optical properties of two-dimensional and three-dimensional photonic crystals based on macroporous silicon is given, and the tunability of the bandgap is demonstrated by changing the refractive index inside the pores caused by an infiltrated liquid crystal undergoing a temperature-induced phase transition.

TL;DR: In this paper, a two-dimensional photonic crystal microresonator based on a single point defect was constructed and two sharp resonances were recorded in the band gap, in excellent agreement with the results of numerical simulations.

TL;DR: Using electrochemical pore formation in n-type silicon, the starting positions of the pores were photolithographically pre-defined to form a hexagonal lattice of a=1.58mm as discussed by the authors.

A novel fabrication method for fluorescence-based apertureless scanning near-field optical microscope probes.
TL;DR: A novel method for the fabrication of probes with localized sub‐wavelength fluorescing media at their extremities is reported and future plans to extend this technique to the systematic fabrication of fluorescent probes for apertureless scanning near‐field optical microscopy are discussed.
