Low-loss optical fibers are now indispensable transmission media for transmission systems. Recently, the ultralow-loss performance for long transmission systems, the water-loss-free performance for wide-band wavelength-division-multiplexing (WDM) sys

The highly nonlinear fiber (HNLF)-based lumped fiber Raman amplifiers (LRAs) for four- and eight-channel coarse wavelength division multiplexing (CWDM) transmission systems have been investigated. By using the developed LRA, the four-channel CWDM tra

Stachyflin is a novel compound having H1 and H2 subtype-specific anti-influenza A virus activity. Stachyflin has no inhibition on H3 subtype influenza A or influenza B viruses. The susceptibility of the reassortant viruses between H1 and H3 subtype i

The authors find that the optical shot noise and the electrical shot noise in light emitting diodes have the identical fluctuation due to spontaneous emission as far as the quantum efficiency is unity. The 0.45-dB reduction of noise below the standar

Nondegenerate four-wave mixing is measured in the 1.5 mu m traveling-wave semiconductor optical amplifier medium as a function of the pump-probe detuning frequency ranging from a few GHz to 400 GHz. It is found that two different sources are responsi

The differential gain and the linewidth enhancement factor of 1.5- mu m multiple-quantum-well (MQW) active layers were measured with and without biaxially compressive strain as functions of the wavelength and the carrier density. These parameters of

By using a hybrid EDFA with a flat gain over 17 nm, two wavelength multiplexed 120 channel AM-VSB signals were successfully transmitted, for the first time, without significant degradation of distortions. This was also realised with the help of a new

Ultra low loss of 0.151dB/km, which is the lowest attenuation ever reported, has been achieved. Its impact on transmission systems with amplifiers such as EDFA and Raman is also examined.
