Amorphous FeCoB alloys can have high resistivity and relatively high saturation magnetization which are desired for ultrahigh frequency devices such as future write heads and wireless inductors.

We have investigated ultrahigh frequency magnetic properties of amorphous Co-Fe-Zr-B alloy films deposited on glass substrates by dc magnetron sputtering.

We have developed an ultrahigh-resolution optical coherence tomographic system in which broadband continuum generation from a photonic crystal fiber is used to produce high longitudinal resolution.

We,demonstrate ultrahigh-resolution optical coherence tomography (OCT) using continuum generation in an air-silica microstructure fiber as a low-coherence light source.

The invention in 1949 by Bardeen, Brattain and Shockley of the bipolar transistor has had tremendous technological ramifications heralding as it did an era of semiconductor microelectronics.

We describe a novel technique for generating ultrahigh-speed bit-by-bit optical phase correlated data signals based on cross-phase modulation induced nonlinear polarization rotation between a pump

We report on dense wavelength-division-multiplexing transmission of 40-Gb/s return-to-zero differential phase-shift keying at distances of 2500 km over conventional nonzero dispersion-shifted fiber

A method of wafer bonding is demonstrated which significantly reduces the thermal expansion mismatch stress, by removing the substrate before the high temperature anneal, thereby allowing elastic a

Today's fiber-optic communications systems use fused-silica based fibers for which signals require reamplification every 30km or so.

Monte Carlo simulations have been used to study the development of ultrametricity in the low temperature phase of the infinite ranged Sherrington-Kirpatrick model of the Ising spin glass.
