Capacity of channels with memory and feedback: Encoder properties and dynamic programming
(2010)This paper is concerned with capacity formulae for channels with memory and feedback, properties of the capacity achieving encoder, and dynamic programming for designing optimal encoders. The source is general and the ...

Effects of Ge concentration, boron co-doping, and hydrogenation on fiber bragg grating characteristics
(2005)In this paper, we compare photosensitivity, refractive-index modulation depth, spectral bandwidth, and excess loss through the inscription of fiber Bragg gratings in unloaded and hydrogen-loaded fibers with low- or ...

Phase shifted Bragg gratings formed in optical fibres by post-fabrication thermal processing
(1996)Fibre Bragg gratings have been post-fabrication processed using localised heat treatment, with significant changes to their transmission and reflection characteristics being observed. Experimental results of the spectral ...

Superimposed multiple Bragg gratings
(1994)The authors demonstrate the inscription of seven Bragg gratings at the same location on a photosensitive fibre. These superimposed Bragg gratings were written over a 60nm span in the region of 1530nm with reflectivities ...
