Nonlinear optical encoding enabled by recurrent linear scattering
Fei Xia, Kyungduk Kim, Yaniv Eliezer +4
Optical information processing and computing can potentially offer enhanced performance, scalability and energy efficiency. However, achieving nonlinearity-a critical component of…
Parallel random LiDAR with spatial multiplexing of a many-mode laser
Kyungduk Kim, Yaniv Eliezer, Olivier Spitz +1
We propose and experimentally demonstrate parallel LiDAR using random intensity fluctuations from a highly multimode laser. We optimize a degenerate cavity to have many spatial mod…
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…
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…
Suppressing meta-holographic artifacts by laser coherence tuning
Yaniv Eliezer, Geyang Qu, Wenhong Yang +5
A metasurface hologram combines fine spatial resolution and large viewing angles with a planar form factor and compact size. However, it suffers coherent artifacts originating from…
Accelerating speckle suppression by a degenerate cavity laser with an intracavity phase diffuser
Simon Mahler, Yaniv Eliezer, Hasan Yılmaz +3
Fast speckle suppression is crucial for time-resolved full-field imaging with laser illumination. Here, we introduce a method to accelerate the spatial decoherence of laser emissio…
Observation of Optical Backflow
Yaniv Eliezer, Thomas Zacharias, Alon Bahabad
Backflow is a counter-intuitive phenomenon in which a forward propagating quantum particle propagates locally backwards. The actual counter-propagation property associated with thi…
Superoscillatory PT-symmetric potentials
Yaniv Eliezer, Alon Bahabad, Boris A. Malomed
We introduce the one-dimensional PT-symmetric Schrodinger equation, with complex potentials in the form of the canonical superoscillatory and suboscillatory functions known in quan…
Particle trapping and conveying using an optical Archimedes' screw
Barak Hadad, Sahar Froim, Harel Nagar +4
Trapping and manipulation of particles using laser beams has become an important tool in diverse fields of research. In recent years, particular interest is given to the problem of…
Super defocusing of light by optical sub-oscillations
Yaniv Eliezer, Alon Bahabad
We show that it is possible to construct spectrally lower bound limited functions which can oscillate locally at an arbitrarily low frequency. Such sub-oscillatory functions are co…
On the fly control of high harmonic generation using a structured pump beam
Lilya Lobachinsky, Liran Hareli, Yaniv Eliezer +2
High harmonic generation (HHG) is an extreme nonlinear frequency up-conversion process during which extremely short duration optical pulses at very short wavelengths are emitted. A…
Breaking the temporal resolution limit by superoscillating optical beats
Yaniv Eliezer, Liran Hareli, Lilya Lobachinsky +2
Band-limited functions can oscillate locally at an arbitrarily fast rate through an interference phenomenon known as superoscillations. Using an optical pulse with a superoscillato…
