OPTICAL FIBER WITH A MICRO BENDING LOSS PROPERTY CAPABLE OF FORMING A PLURALITY OF TRENCHES WITH A REPEATED FREQUENCY IN A CORE AREA

摘要

PURPOSE: An optical fiber with a micro bending loss property is provided to efficiently reduce a cutoff wavelength by using the tunneling effect of a high dimension mode by a plurality of trenches.;CONSTITUTION: An optical fiber includes a core area(1). The core area is composed of a first core area(1a), a second core area(1b), and a third core area(1c). The second core area is surrounded with the first core area. The third core area has a refractive index distribution with a plurality of trench structures and is surrounded by the second core area.;COPYRIGHT KIPO 2012
