Abstract
This paper presents the design of a W-type index chalcogenide fiber for mid-infrared beyond 10μm. The main advantages of the W-type index fiber are the possibility to control the chromatic dispersion with a larger possible core area for single-mode operation compared to a common step-index fiber and...
