Temperature-Insensitive Bend Sensor Using Entirely Centered Erbium Doping in the Fiber Core

Temperature-Insensitive Bend Sensor Using Entirely Centered Erbium Doping in the Fiber Core

A fiber based bend sensor using a uniquely designed Bend-Sensitive Erbium Doped Fiber (BSEDF) is proposed and demonstrated. The BSEDF has two core regions, namely an undoped outer region with a diameter of about 9.38 μm encompassing a doped, inner core region with a diameter of 4.00 μm. The doped co...
