All-optical AND gate based on coupled gap-soliton formation in a fiber Bragg grating.

Optics letters

Taverner D, Broderick NG, Richardson DJ, Ibsen M, Laming RI.
PMID: 18084478
Opt Lett. 1998 Feb 15;23(4):259-61. doi: 10.1364/ol.23.000259.

We experimentally demonstrate an all-optical AND gate based on coupled gap-soliton formation in an apodized fiber Bragg grating. A switching contrast of better than 17 dB is obtained with an incident pulse peak power of 2.5 kW.

PMID: 19384393
Opt Express. 1998 Nov 23;3(11):447-53. doi: 10.1364/oe.3.000447.

We report on our recent experiments on nonlinear switching in fibre Bragg gratings. Using an all-fibre source we show an increase in transmission of a FBG from 4% to 40% at high powers. This switching is associated with the...

Electrospray ionization (ESI) of solutions containing adenine and AgNO(3) yields polymeric [Ad(x)+ Ag(y)-zH]((y-z)+) species. Density functional theory (DFT) calculations have been used to examine potential structures for several of the smaller ions while multistage mass spectrometry experiments have been...
