We experimentally demonstrate deterministic tuning of photon statistics and controlled bunching of photons in off-diagonal disordered lattices. We achieve this by gradually activating the chiral mode pairs with a coherent structured illumination.
The charged version of Majorana particles are unphysical and due to the violation of charge conservation they can not exist. However, we experimentally emulate the dynamics of charged Majorana particles in a tailored waveguide chip.
We present a method for controlling the sign of the coupling term for individual links in arbitrary tight-binding lattices. The scheme employs defect insertion and eigenmode matching and is experimentally verified in photonic lattice implementations.
We introduce a new perfect state transfer protocol based on single-photon W-eigenstates of photonic lattices. Such W-eigenstates appear as impulse response of the system, e.g., when single photons are launched into single sites.
We predict and observe the formation of a compact surface bound state in the continuum due to an optical Fano resonance. We employ a one-dimensional array of optical waveguides with an additional side-coupled waveguide inducing the resonance, and prove that the localized mode amplitude vanishes completely at all locations beyond the resonant waveguide.
We demonstrate photonic lattices with segmentation-based linear self imaging as integrated optical limiters. The diffractive propagation between input and output port offers the additional benefit of substantially decreased nonlinear spectral distortions.
We report the first observation of classical Bloch-like oscillations and revivals of light in a new class of dynamic optical systems-the so-called Glauber-Fock oscillator lattices.
We demonstrate that the eigenmodes of a waveguide array with disorder in the coupling between adjacent guides are pairwise conjugated. Therefore, self-imaging via phase-segmentation is inherently insensitive to such an off-diagonal disorder.
We introduce a multiport waveguide array beam-splitter that emulates the action of the angular momentum matrix Jx. Quantum transformations carried out by such devices are discussed and pertinent examples are provided.
We investigate the impact of nonlinearity on the perfect imaging by segmentation in photonic lattices with disorder. We find the presence of strongly localized Anderson modes renders the imaging significantly more susceptible to nonlinear perturbations.
In quantum mechanics, a displacement in phase space of the ground state of the harmonic oscillator generates a coherent state [1]. Average positions and momenta of these minimum-uncertainty states describe the motion of a classical oscillator, thereby building an important bridge to classical mechanics. In a similar fashion, more general states can be obtained when higher eigenstates of the oscillator...
We report the first observation of classical intensity distributions in optical arrays that are totally analogous to quantum coherent and displaced Fock states. Bloch-like oscillations and revivals are also predicted in such Glauber-Fock photonic lattices.
We present, theoretically and experimentally, amorphous photonic lattices exhibiting band gap and negative effective mass, yet lacking Bragg diffraction. Here, bands comprise of Anderson states, but defect states residing in the gap are always more localized.
We present the results of our investigations on the formation process of nanogratings in fused silica and the influence of fabrication parameters, thereby identifying ways to systematically control the grating properties. Nanogratings, self-organized nanostructures with subwavelength periodicity, are formed in certain parameter ranges during femtosecond-laser processing of transparent materials, resulting...
Fluorine-18 labeled 2β-carbomethoxy-3β-(4-chlorophenyl)-8-(2-fluoroethyl)nortropane (FECNT) was synthesized in the development of a dopamine transporter (DAT) imaging ligand for positron emission tomography (PET). The methods of radiolabeling and ligand synthesis of FECNT, and the results of the in vitro characterization and in vivo tissue distribution in rats and in vivo PET imaging in rhesus monkeys...
