Instabilities, breathers and rogue waves in optics

JM Dudley, F Dias, M Erkintalo, G Genty - Nature Photonics, 2014 - nature.com
Optical rogue waves are rare, extreme fluctuations in the value of an optical field. The
term'optical rogue wave'was first used in the context of an analogy between pulse …

Optofluidic time-stretch imaging–an emerging tool for high-throughput imaging flow cytometry

AKS Lau, HC Shum, KKY Wong, KK Tsia - Lab on a Chip, 2016 - pubs.rsc.org
Optical imaging is arguably the most effective tool to visualize living cells with high
