Fiber device having variable refractive index region proximal the core |
摘要 |
A device for changing the power levels of signals transmitted by an optical fiber, along with signal modulation and wavelength routing, comprises a length of optical fiber in which for a predetermined section of the length of the fiber, the fiber core is surrounded by a cladding having one or more variable refractive index (VRI) regions disposed therein in close proximity to the core. The VRI regions are fabricated with a material having an index of refraction higher than that of the cladding and may comprise a variable attenuator. <IMAGE> |
