In this work, we report the experimental observation of supercontinua generation in two kinds suspended-core microstructured soft-glass optical fibers. Low loss, highly nonlinear, tellurite and As2S3 chalcogenide fibers have been fabricated pumped close to their zero-dispersion wavelength femtosecond regime by means an parametric oscillator a Ti:Sapphire laser. When coupled into fibers, pulses result 2000-nm bandwidth reaching Mid-Infrared region extending from 750 nm 2.8 µm 1 3.2 respectively.
Abstract Recent research has been focused on the ability to manipulate a light beam in such way hide, namely cloak, an event over finite time or localization space. The main idea is create hole gap spatial domain so as allow for object data be kept hidden while and then restored.

In this contribution, we review our recent progress on the all-optical control of state-of-polarization light in optical fibers upon propagation a system called Omnipolarizer. More precisely, device exploit unexpected capability to self-organize its own state-of-polarization, fibers, into universal and environmentally robust states. The underlying physical mechanism consists nonlinear cross-polarization feedback interaction between an arbitrary polarized incident signal counter-propagating...

The combination of nonlinear and integrated photonics enables applications in telecommunication, metrology, spectroscopy, quantum information science. Pioneer works silicon-on-insulator (SOI) has shown huge potentials photonics. However, silicon suffers two-photon absorption (TPA) the telecom wavelengths around 1550 nm, which hampers its practical applications. To get a superior performance, an ideal waveguide platform should combine high material nonlinearity, low (linear nonlinear), strong...

We analyze two all-optical fiber-based fast polarization scramblers. In the first, a signal beam nonlinearly interacts with co-propagating incoherent pump, whose temporal fluctuations induce an effective depolarization of signal. second, its backward replica generated and amplified by reflective loop. Beyond amplification threshold, output exhibits chaotic dynamics.
