Bi:SiO 2 optical fibers – a possible way to understand the nature of Bi-related emitting centers
Fiber materials Fiber optics amplifiers oscillators Lasers fiber
2011/5/22
Excitation-emission properties of Bi:SiO 2 optical fibers (without other dopants) were investigated in the wavelength region 400-1600nm. Laser generation in fibers of such composition was demonstrated...
Nature of lossy Bloch states in polaritonic photonic crystals
lossy Bloch states polaritonic photonic crystals
2004/8/11
We examine the effects of absorption losses in photonic crystal structures composed of polar materials which exhibit transverse phonon-polariton excitations. In order to explore the Bloch states of su...
