We consider the selective injection of active material into a 2-D photonic crystal. Using an alumina nanohole array as a base photonic crystal, we fabricated a positional-selective through-hole in the array with a focused ion beam. The active materia

A two dimensional (2D) GaAs hole array with a high aspect ratio was successfully fabricated by dry etching techniques using a highly ordered alumina membrane as a mask. The reflection spectra of the GaAs hole array shows characteristics of the photon

Two-dimensional photonic crystals (2D-PhCs) on oxide can be easily incorporated into photonic integrated circuits. Although an asymmetrical structure (air/PhC/oxide) is advantageous in terms of ease of fabrication, it has been pointed out that such a

SiO2/air three-dimensional (3D) periodic structures were fabricated by removing Si layers partially from Si/SiO2 3D photonic crystals (PhCs) formed by using autocloning. CdS/SiO2 3D periodic structures were formed by introducing CdS into the SiO2/air

Synchrotron radiation alters the refractive index of fluorinated polyimide, and it is possible to adjust the refractive index to within 10–2 by varying the irradiation dose. The chemical condition of the polyimide after irradiation was investigated

We propose two photonic crystal structures that can be created by combining nanolithography with alternating-layer deposition. Photonic band calculations suggest that a drilled alternating-layer photonic crystal combining two-dimensional (2D) alterna

We fabricate photonic crystals for the visible range by the ‘autocloning’ technique, in which multilayers are stacked by an appropriate combination of sputter deposition and sputter etching. TiO2/SiO2 and Ta2O5/SiO2 are chosen as materials since

We mainly discuss the self-organization in a strained InGaAs/AlGaAs system on a GaAs(311)B surface. This self-organizing growth mode in metal–organic–vapor phase epitaxy automatically produces very small confined nanostructure of quantum disks du
