| 研究実績の概要 |
More than one hundred calculations of fiber structures were done to study the suppression of chromatic dispersion variation by adding a buffer layer to the hybrid microstructured optical fiber (HMOFs). By using chalcogenide buffer-HMOF, the supercontinuum generation spectrum can be extended from 2 up to about 16 um and can be maintained in the presence of ±1 % fiber fluctuation. By using tellurite buffer-HMOFs, when core diameter fluctuation was ± 40 nm, the variation of optical parametric amplification (OPA) spectrum from about 1.40 to 2.7 um can be suppressed. When fiber diameter fluctuation was ±1%, OPA spectrum was enhanced in both spectral bandwidth and intensity.
The results were published in conferences of SPIE Photonics West, CLEO USA, ICETE Spain and Optical Review journal in 2017.

1: 当初の計画以上に進展している
理由
In 2017, we have achieved the targets which we planned before in our proposal. They include:
1. Design and simulation of fiber microstructures which can suppress the chromatic dispersion variation by using buffer-hybrid microstructured optical fibers (HMOFs).
2. Study the potential performances of supercontinumm generation in chalcogenide buffer-HMOFs.
3. Study the potential performances of optical parametric amplification in tellurite buffer-HMOFs.
Moreover, we have started to develop glass materials for buffer-HMOFs experimentally.

| 今後の研究の推進方策 |
In 2018, we will continue the development of glass materials for core, cladding and buffer layers of buffer-hybrid microstructured optical fibers (HMOFs).
The fiber fabrication will be carried out and the performances of chromatic dispersion, supercontinuum generation and optical parametric amplification will be investigated experimentally.
