We present a novel fiber-based near-field optical head consisting of a straw-shaped writing probe and a flat gap sensing probe. The strawshaped probe with a C-aperture on the end face exhibits enhance...
Linear superpositions of gap solitons in periodic Kerr media
Linear superpositions gap solitons periodic Kerr media
2011/8/3
Abstract: The existence of a novel type of solitons in periodic Kerr media constructed as superposition of noninteracting gap-solitons of different kinds (bright, dark and periodic) is first demonstra...
Inhibited spontaneous emission of quantum dots observed in a 3D photonic band gap
3D photonic band gap spontaneous emission
2011/8/31
We present time-resolved emission experiments of semiconductor quantum dots in silicon 3D inverse-woodpile photonic band gap crystals. A systematic study is made of crystals with a range of pore radii...

Second harmonic Nonlinear frequency phosphide photonic crystal
2011/8/26
We demonstrate enhanced second harmonic generation in a gallium phosphide photonic crystal waveguide with a measured external conversion eciency of 5107/W. Our results are promising for fr...
Progress towards fabrication of Th:229-doped high energy band-gap crystals for use as a solid-state optical frequency reference
Th:229-doped high energy band-gap crystals solid-state optical frequency
2010/11/12
We have recently described a novel method for the construction of a solid-state optical frequency reference based on doping $^{229}$Th into high energy band-gap crystals. Since nuclear transitions ar...
