Günter Steinmeyer Rogue waves in optics and beyond

Ocean rogue waves are extremely large waves that defy Gaussian statistics. They may exceed the significant wave height by factors 2 or larger, resulting in wave heights of 30 meters or higher, and can severely damage ships or other maritime structures. In contrast to tsunamis, mechanisms behind the formation of rogue waves are still disputed, and opinions differ whether and how such waves can be predicted. To this end, it has proven helpful that optical experiments may also show similar non-Gaussian statistics. Moreover, these experimental schemes can produce hundreds of individual rogue events within seconds of observation. Based on these large sets of rogue events, one can easily verify the hypothesis of a predictability of rogue waves. To our surprise, we found that there are two different classes of rogue waves, which either originate from quantum fluctuations or arise due to turbulence. Ocean rogue waves belong to the latter class and are therefore predictable. Nevertheless, indications are that this predictability is of little practical use, and warnings may only be possible a few seconds before the rogue wave actually strikes. Finally, optical experiments also deliver an explanation for the ocean rogue wave phenomenon, and it seems that their origin is simply linear random interference of a finite number of elementary waves. If proven true, this explanation may enable at least a forecast for their appearance probability, even if prediction of the individual rogue wave may stay illusional.

Chih-Hsuan Lu Award Candidate Sub-3-fs multi-GW Pulses Produced from MPContinuum

An octave-spanning supercontinuum generated in an all-solid-state multiple-plates arrangement has been compressed to yield near-single-cycle pulses that are 2.78 fs in duration and that have 5.9 GW peak power.

Pei-Chi Huang Award Candidate EUV continuum generated from a compressed supercontinuum pulse produced in a set of thin fused silica plates

A one-cycle (3.3 fs) pulse compressed from a set of thin plates generated supercontinuum has been demonstrated and used to produce a bright EUV continuum with 5×10-5 up-conversion efficiency ranging from 43 to 65 eV, supporting an isolated, transform-limited pulse of 190 attoseconds.

Dung-Han Yeh Award Candidate Optical Frequency Variation Control of a 10GHz Asynchronous Harmonic Mode-Locked Fiber Soliton Laser with CW Laser Injection

Stable operation of asynchronous harmonic mode-locking can still be maintained under appropriate CW laser injection. The optical frequency variation of the 10GHz mode-locked fiber laser can be reduced by a factor of 5 with injection.

Sheng-Min Wang Award Candidate Polarization Maintaining Passive Mode-Locked Er-Fiber Laser Based on Nonlinear Amplifying Loop

An environmentally stable all-fiber polarization maintaining passive mode-locked Er-doped fiber laser based on a nonlinear amplifying fiber loop is investigated. We have successfully obtained ps order stable mode-locked pulse trains and have also observed interesting mode-locking phenomena including multiple pulses and noise-like pulses.
