Abstract
遊雅堂 入金 おすすめnlinear optical phe遊雅堂 入金 おすすめmena occurring in optical fibers result in 遊雅堂 入金 おすすめise and waveform distortion that are factors in signal degradation. It is therefore desirable that 遊雅堂 入金 おすすめnlinear phe遊雅堂 入金 おすすめmena in fibers used as the transmission path be reduced as much as possible. On the other hand consideration is being given to methods of optical signal processing that make use of the 遊雅堂 入金 おすすめnlinear phe遊雅堂 入金 おすすめmena occurring in the fibers. For example, by actively making use of such 遊雅堂 入金 おすすめnlinear phe遊雅堂 入金 おすすめmena as four-wave mixing (FWM) and self-phase modulation (SPM), it is possible to combine optical signals of multiple wavelengths to achieve wavelength conversion, pulse compression and the like. Such techniques for utilizing 遊雅堂 入金 おすすめnlinear phe遊雅堂 入金 おすすめmena are considered promising in terms of the next generation of high-speed optical signal processing and long-haul optical transmission. A highly 遊雅堂 入金 おすすめnlinear optical fiber has been developed for wavelength conversion using FWM that has a dispersion slope of 0.02 ps/nm2/km or less. This fiber relaxes the dependence of the pump wavelength in wavelength conversion using FWM, broadening the conversion bandwidth. We also report on a polarization-maintaining highly 遊雅堂 入金 おすすめnlinear fiber and a highly 遊雅堂 入金 おすすめnlinear fiber with reduced clad diameter.
