We show that the efficiency and the mismatch bandwidth of quadratic soliton formation under conditions of second-harmonic generation can be enhanced in an important way in synthetic phase-matching profiles. Soliton excitation ...

We present a proof-of-concept experiment aimed at increasing the sensitivity of temperature sensors implemented with Fiber Bragg gratings by making use of a weak value amplification scheme. The technique requires only ...

We show that the sensitivity and robustness of a label-free optical imaging technique based on stimulated Raman scattering (SRS) can be enhanced by using resonant optical transitions in a Raman adiabatic passage scheme. ...

Entangled photons are generally collected by detection systems that select their certain spatial modes, for example using single-mode optical fibers. We derive simple and easy-to-use expressions that allow us to maximize ...

Coherent frequency conversion of structured light, i.e. the ability to manipulate the carrier frequency of a wave front without distorting its spatial phase and intensity profile, provides the opportunity for numerous novel ...

There is renewed interest in using the coherence between beams generated in separate down- converter sources for new applications in imaging, spectroscopy, microscopy and optical coherence tomography (OCT). These schemes ...

The propagation of stationary three-dimensional nonlinear guided waves and of Gaussian beams in a slab waveguide in which the cladding displays both Kerr-law and saturable instantaneous self-focusing nonlinearities is ...

The impact of temporal effects to the generation of multiple wave quadratic spatial solitons with pulsed light is shown. We examine soliton formation under conditions of second-harmonic generation but our conclusions are ...

The guided-to-leaky hybrid mode transition in slab optical waveguides made on uniaxial crystals such as LiNbO/sub 3/, or LiTaO/sub 3/, is analyzed. Two different guided-to-leaky transitions have been identified, namely the ...
