Controlling light propagation in multimode fibers for imaging, spectroscopy and beyond
Hui Cao, Tomáš Čižmár, Sergey Turtaev +2
Light transport in a highly multimode fiber exhibits complex behavior in space, time, frequency and polarization, especially in the presence of mode coupling. The newly developed t…
Mitigating stimulated Brillouin scattering in multimode fibers with focused output via wavefront shaping
Chun-Wei Chen, Linh V. Nguyen, Kabish Wisal +9
The key challenge for high-power delivery through optical fibers is overcoming nonlinear optical effects. To keep a smooth output beam, most techniques for mitigating optical nonli…
Exploiting structural nonlinearity of a reconfigurable multiple-scattering system
Yaniv Eliezer, Ulrich Ruhrmair, Nils Wisiol +2
Nonlinear optics is a rapidly growing field that has found a wide range of applications. A major limitation, however, is the demand of high power, especially for high-order nonline…
Suppressing transverse mode instability through multimode excitation in a fiber amplifier
Chun-Wei Chen, Kabish Wisal, Yaniv Eliezer +2
High-power fiber laser amplifiers have enabled an increasing range of applications in industry, medicine and defense. The power scaling for narrow-band amplifiers is currently limi…
Sensitive control of broad-area semiconductor lasers by cavity shape
Kyungduk Kim, Stefan Bittner, Yuhao Jin +5
The ray dynamics of optical cavities exhibits bifurcation points: special geometries at which ray trajectories switch abruptly between stable and unstable. A prominent example is t…
Controlling nonlinear interaction in a many-mode laser by tuning disorder
Yaniv Eliezer, Simon Mahler, Asher A. Friesem +2
A many-mode laser with nonlinear modal interaction could serve as a model system to study many-body physics. However, precise and continuous tuning of the interaction strength over…
Customizing the angular memory effect for scattering media
Hasan Yılmaz, Matthias Kühmayer, Chia Wei Hsu +2
The memory effect in disordered systems is a key physical phenomenon that has been employed for optical imaging, metrology, and communication through opaque media. Under the conven…
Super- and Anti-Principal Modes in Multi-Mode Waveguides
Philipp Ambichl, Wen Xiong, Yaron Bromberg +3
We introduce a new type of states for light in multimode waveguides featuring strongly enhanced or reduced spectral correlations. Based on the experimentally measured multi-spectra…
Using geometry to manipulate long-range correlation of light inside disordered media
Raktim Sarma, Alexey Yamilov, Pauf Neupane +1
We demonstrate experimentally that long-range intensity correlation for light propagating inside random photonic waveguides can be modified by changing the shape of the waveguide.…
Rotation-induced Asymmetry of Far-field Emission from Optical Microcavities
Li Ge, Raktim Sarma, Hui Cao
We study rotation-induced asymmetry of far-field emission from optical microcavities, based on which a new scheme of rotation detection may be developed. It is free from the "dead…
Lasing in localized modes of a slow light photonic crystal waveguide
Jin-Kyu Yang, Heeso Noh, Michael J. Rooks +3
We demonstrate lasing in GaAs photonic crystal waveguides with InAs quantum dots as gain medium. Structural disorder is present due to fabrication imperfection and causes multiple…
Five-Fold Reduction of Lasing Threshold near the First -Pseudogap of ZnO Inverse Opals
Michael Scharrer, Heeso Noh, Xiaohua Wu +4
We report room temperature lasing in ZnO inverse opal photonic crystals in the near-ultraviolet (UV) frequency. We observe random lasing due to disorder in the structures when the…
