摘要:
A technique is described for fabricating one or more optical devices in a carbon-coated optical fiber. A photosensitive optical fiber is provided having a hermetic carbon coating. Further provided is a laser having a beam output that is configured to inscribe one or more refractive index modulations into the optical fiber through the hermetic carbon layer while leaving the hermetic carbon layer intact. The laser is used to inscribe one or more optical devices into the optical fiber through the hermetic carbon layer.

摘要:
In an optical fiber turnaround, first and second optical fiber cores are configured to transmit light bidirectionally along a transmission axis between proximal and distal ends of the first and second optical fiber cores. A reflector component is positioned at the distal ends of the first and second optical fiber cores. The first core, second core, and reflector component are configured to provide a bidirectional routing path, wherein light energy travels from the proximal end of one of the first and second cores towards the reflector component, and travels back from the reflector component along the other of the first and second cores.

摘要:
An optical fiber includes a large graded index core of Ge doped silica for an increased bandwidth-length-product of over 100 MHz-km. A cladding layer of non-doped silica is formed on the core during the preform process and subsequently during drawing the preform an ultraviolet light curable polymer first coating is overlaid on the cladding layer. The first coating is sufficiently hardened to match the fracture characteristics of the silica core and cladding layer to facilitate crimp and cleave termination. The first coating is additionally provided with an index of refraction greater than the cladding layer to enable mode or energy stripping from the cladding layer. A second polymer layer may optionally be applied during draw for protection and to provide a tough outer layer of the optical fiber for the deformable features of a connector to hold onto after crimping.
