Chalcogenide microwire based Raman laser

Applied Physics Letters, 2012
We present a Raman fiber laser based on a chalcogenide glass microwire. The microwire is pumped in the C-band, and the resulting laser oscillates in the L-band. The power conversion efficiency of the device is ∼17%, and the laser threshold is 23.2 dBm (pulse energy = 4.65 pJ) in peak pump power.

Determining Microwire Morphology and Current Transient Trends from Single Microwire Electrodeposition

ECS Meeting Abstracts, 2015
This presentation describes work on understanding and controlling the electrochemical liquid-liquid-solid (ec-LLS) process for the preparation of crystalline semiconductor materials. In this work, data are presented to test the hypothesis that the current-time transient collected during a potentiostatic ec-LLS deposition of Ge microwires contains ...

Effect of Microwires Diameters on the Microwave Properties of Glass-Coated Microwires/Dielectric Composite

Advanced Materials Research, 2013
The microwave properties of Glass-coated FeCuNbVSiB and CoFeNiSiB microwires/dielectric composite with different microwires diameters were studied. Relative complex permeability and complex permittivity was measured by transmission/reflection (T/R) coaxial line method at the frequency range of 2-18 GHz for composite samples.

Detection of a Ferromagnetic Microwire

2012
Abstract : This report, which supplements the material presented in the IEEE Transactions in Magnetics publication entitled Two-Frequency Excitation of a Ferromagnetic Microwire, describes a simple configuration of antenna beams, polarizations, and wire placement calculations, which are used in calculating the response of a magnetic wire to ...

Magnetoelastic anisotropy of amorphous microwires

Journal of Magnetism and Magnetic Materials, 2003
Anisotropy constants of amorphous microwires with positive, negative, and nearly zero magnetostriction, are calculated as function of wire dimensions starting from the distribution of internal stresses induced during preparation. Some basic aspects of their magnetic behavior are subsequently discussed, in correlation with earlier experimental results.

Interference and Noise in Human Intracranial Microwire Recordings

IEEE Transactions on Biomedical Engineering, 2009
Human intracranial microwire recordings have typically had poor signal-to-noise ratios (SNRs), often below 10 dB. The physiological signal source is a fixed-amplitude one; thus, SNR must be improved by reducing either noise or interference. An understanding of the interference sources, how they are coupled to the recording system, and their relative ...

Magnetic Properties of Nanocrystalline Microwires

Journal of Electronic Materials, 2015
We have studied magnetic properties of Finemet-type and Hitperm-type microwires. In the case of the Finemet-type we observed that GMI effect and magnetic softness of microwires can be considerably improved by annealing. A considerable GMI effect has been observed in annealed FeCuNbSiB microwires exhibiting nanocrystalline structure. From the dependence
