Abstract
In-line fiber optic structure devices for use as environmental sensors and methods of fabricating in-line fiber optic structures as environmental sensors are disclosed and provided. According to some embodiments, fiber optic sensor devices can utilize the interaction of surface plasmons or evanescent waves with a surrounding environment. Fiber optic sensors according to some embodiments of the present invention provide an optical fiber with a long environmental interaction length having improved structural integrity. Graded-index optical fiber elements can be used as lenses and a coreless optical fiber element can act as an environmental interaction or sensing area. Graded-index and coreless optical elements can be fused to provide a continuous fiber optic sensing system. Other various embodiments are also claimed and described.
