An integrated optic structure is proposed in order to make Kerr-like nonlinear interactions practical for optical signal processing applications. The interacting electric fields propagates as different modes of a multimode waveguide, and couple to ea

An experimental demonstration of an energy limiter for short pulses at 1550 nm is reported. The limiter is based on an optical fiber Sagnac loop with an intraloop dichroic saturable absorber based on an InGaAsP-based waveguide with compressively stra

The GdBa 2− x La x Cu 3 O 7 series has been prepared and studied by XRD, magnetic a.c. susceptibility and microwave absorption. The transition temperature T c , as a function of the doping level, shows a nonlinear variation in two steps indicating

We experimentally demonstrate filtering based on the finite time response of the interband carrier nonlinearities in a direct bandgap semiconductor. The filter is implemented in a mixed strain polarization insensitive multiple-quantum-well, broad-are

Applied static fields increase the width of the diamagnetic susceptibility χ ' ( T ) transition and decrease the irreversibility line temperature T m ( H ): those effects which can be related to intergrain and interplane couplings are amplified by t

After a short review of the main properties for the classical superconductors, we analyze the atomic structure of two dimensional character, the electronic structure and the magnetism of the new superconducting oxides with copper. Their origins can b

Electrical resistivity measurements of NdH2+x show the effects of a structural order-disorder transition, related to the excess H concentration x, for which we give information on the ordering temperature, T s, and the stabilizing effects of quenchin

High power and high energy ultrashort pulse generation with a frequency shifted feedback fiber laser
Publikováno v:
Optics express. 15(24)
The highest average power that has been achieved with a frequency-shifted feedback modelocked fiber laser is reported. Subpicosecond pulses with 40 kW peak power are obtained by this technique for the first time by using external pulse compression. T

A nonequilibrium Mg hydride was prepared by low temperature hydrogen implantation in Mg thin films. In contrast to the usual compound in which H is charged under high pressure and elevated temperature, no structural phase transformation from hexagona
