Soliton-effect compression of supercontinuum to few-cycle durations in photonic nanowires
TLDR
By exploiting the broad region of anomalous group-velocity dispersion and the large e.ective nonlinearity of photonic nanowires, soliton-e.ect self-compression of 70-fs pulses down to 6.8 fs is demonstrated.Abstract:
By exploiting the broad region of anomalous group-velocity dispersion (GVD) and the large effective nonlinearity of photonic nanowires, we demonstrate soliton-effect self-compression of 70-fs pulses down to 6.8 fs. Under suitable conditions, simulations predict that self-compression down to single-cycle duration is possible.read more

Silicon Nanowire Embedded Spiral Photonic Crystal Fiber for Soliton-Effect Pulse Compression
TL;DR: In this article, the authors proposed a new type of optical waveguide called silicon nanowire embedded equai-angular spiral photonic crystal fiber (SN-SPCF) using fully vectorial finite element method, where closely arranged arrays of air holes act as cladding and nanosize silicon material at the centre acts as core.
Optical nonlinear interactions in dielectric nano-suspensions
TL;DR: In this paper, the Nernst-Planck and Smoluchowski equations of colloidal systems were analyzed for both 1D and 2D configurations and their propagation dynamics in the presence of Rayleigh losses was examined.

TL;DR: In this paper, a supercontinuum generation in microstructure fiber with six submicron-diameter cores, surrounding a larger central core, is demonstrated, which is promising for increasing the total energy of supercontinuity emission and fabricating micro-structure-integrated arrays of small-core high-index-step fibers with large lengths.

Low dispersion and high nonlinearity microstructured photonic quasicrystal fiber
Abstract: We propose a six fold solid-core photonic quasicrystal fiber for studying optical properties for wavelengths from 200 to 3000 nm and demonstrate a low dispersion and high nonlinearity at 1060 nm for few-cycle pulse generation.

TL;DR: High-energy 20-fs pulses generated by a Ti:sapphire laser system were spectrally broadened to more than 250 nm by self-phase modulation in a hollow fiber filled with noble gases and subsequently compressed in a broadband high-throughput dispersive system, resulting in the shortest generated to date at multigigawatt peak powers.
