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...
Efficient Guiding of Cold Atoms though a Photonic Band Gap Fiber
Efficient Guiding Cold Atoms Photonic Band Gap Fiber
2010/10/29
We demonstrate the first guiding of cold atoms through a 88 mm long piece of photonic band gap fiber. The guiding potential is created by a far-off resonance dipole trap propagating inside the fiber w...
Universal features of coherent photonic thermal conductance in multilayer photonic band gap structures
Universal features photonic thermal conductance multilayer photonic band gap structures
2015/8/10
We show that at the high-temperature limit, the coherent photonic thermal conductance of a multilayer photonic crystal can be significantly below the corresponding thermal conductance of vacuum....

2011/5/6
The transmission properties in microwave domains (10 GHz to 40 GHz) of generalized dielectric Fibonacci multilayer generated by the rule Sl+1 = SmlSnl–1: with a pair of positive integers m and n were ...
Multipole-cancellation mechanism for high-Q cavities in the absence of a complete photonic band gap
Multipole-cancellation mechanism high-Q cavities complete photonic band gap
2015/8/12
We describe and demonstrate a new mechanism for low radiation losses in structures lacking a complete band gap, and show how resonant cavities with Q.103 can be achieved without sacrificing stro...
