TL;DR: A systematic process of theoretical design and experimental fabrication of the large mode area and large negative dispersion photonic crystal fiber is presented and an easily fabricated fiber structure is proposed.

TL;DR: A new kind of white light emitting glass suitable for long-wavelength ultraviolet excitation by simultaneously emitting blue, green and red fluorescence, which is fabricated by melting of Ce(3+))-Tb(3+)-Mn(2+) co-doped borosilicate glass is reported.

TL;DR: In this paper, a facile method to tailor clusters of active ions by using one kind of porous host, the nanoporous silica glass, was presented by sintering of nanoporous glass impregnated with Ce3+, Tb3+, Mn2+ and Al3+ ions.

TL;DR: A new kind of green-emitting high silica luminous glass, fabricated by sintering of Ce(3+)-Tb(3+) co-doped porous glass, where the role of Ca(2+) has been discussed, and the fluorescence decay curve reveals that the Ca( 2+) play an important role in energy transfer.

TL;DR: A double negative curvature anti-resonance hollow core fiber, in which, the cladding is constituted of 6 large tubes and 6 small tubes arranged in a staggered pattern, with the best single mode performance with a loss ratio as high as 100,000 between LP11 mode and LP01 mode is obtained.
