Microhole-structured Long Period Fiber Grating
An optical fiber with long period fiber gratings includes an optical fiber axis, a core region extending along the fiber axis, the core region having a core refractive index, a cladding region surrounding the core region, the cladding having a cladding refractive index, and a plurality of microholes perpendicular to the fiber axis with a portion of the core region removed, the plurality of microholes are spaced apart by a grating period.

Title: Microhole-structured long period fiber grating
Usefulness: Microhole-structured long period fiber grating
Summary: Optical fiber e.g. microhole-structured long period fiber grating (LPFG) optical fiber, single mode fiber (SMF) and micro-structured fiber such as photonic-crystal fiber (PCF) and photonic-bandgap fiber (PBGF).
Novelty: Optical fiber e.g. microhole-structured long period fiber grating optical fiber, has microholes placed perpendicular to fiber axis with portion of core region from being removed and spaced apart by grating period
