Wave-breaking-extended fiber supercontinuum generation for high compression ratio transform-limited pulse compression [PDF]
Optics Letters, 2012 Wave-breaking often occurs when a short intense optical pulse propagates in a long normally dispersive optical fiber. This effect has conventionally been avoided in fiber (super-)continuum-based pulse compression because the accumulated frequency chirp of the output pulse cannot be fully compensated by a standard prism (or grating) pair.

On a high performance image compression technique [PDF]
, 2013 We introduce an optimal approach to colour image compression using a new scan method. We propose efficient methods to increase the compression ratio for colour images by dividing the colour image into non-overlapping blocks and applying a different ...
