| 摘要 |
An eccentric core optical fiber 10 having a cross-sectional area sufficiently large to afford ease of manipulation, yet deposed to operate in an evanescent mode, is disclosed herein. The inventive optical fiber 10 includes a fiber core 20 of a first index of refraction. The fiber core 20 circumscribes a first longitudinal axis. The optical fiber 10 of the present invention further includes fiber cladding material 30 of a second index of refraction chosen to be less than the first index of refraction. The cladding material 30 circumscribes both a fiber core 20 and a second longitudinal axis oriented parallel to but not coincident with the first longitudinal axis.
