Optical measurement of trapped acoustic mode at defect in square-lattice photonic crystal fiber preform
TL;DR: In this article, the authors presented the first experimental demonstration of an acoustic defect mode trapped at the solid core in a square-lattice Photonic crystal fiber preform, where the core can act as a defect of the phononic crystal and so elastic defect modes can be confined in this region.
Proceedings ArticleDOI
Suppressed mode recovery in nonlinear fibers of a Fabry-Perot-filtered frequency comb

TL;DR: In this article, a Yb-fiber based frequency comb spanning more than 150 nm with a multi-GHz mode spacing was set up for dynamic reamplification of suppressed modes in a nonlinear fiber after the filter cavities was observed and analyzed.
Proceedings ArticleDOI
A study of UV photosensitivity in germanosilicate preforms and fibres
TL;DR: In this paper, the authors have studied the dynamics of the absorption changes in germanosilicate preforms and have also simulated the index change growth in fibre gratings, finding that the index modulation for the first order Bragg gratings can only reach 20% of the maximum index change at F=-2F/sub 0/ and decreases for longer exposure times.
Book ChapterDOI
Dispersion, Tunability and Applications of Defect Modes in Photonic Band-Gap Structures
TL;DR: In this article, the DFB laser mode supported by a structural defect at the centre of a uniform Bragg mirror is described. But the frequency of the resonant frequency of this mode lies within the photonic bandgap of the mirror.
Proceedings ArticleDOI
Highly-efficient cw blue light generation via first-order quasi-phase-matched frequency doubling of a diode-pumped 946 Nd:YAG laser
TL;DR: In this paper, first-order quasi-phase matched frequency doubling of a high-power diode-pumped 946 nm Nd:YAG laser was used to generate blue light with a conversion efficiency of 4.6%.
