| Outline of Annual Research Achievements |
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.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
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.

| Strategy for Future Research Activity |
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.
