Abstract
Herein is provided a fiber that includes a cladding material disposed along a longitudinal-axis fiber length and a plurality of discrete and disconnected high-stress domains that are disposed as a sequence along a longitudinal line parallel to the longitudinal fiber axis in at least a portion of the fiber length. Each high stress domain has an internal pressure of at least 0.1 GPa and comprises a material that is interior to and different than the fiber cladding material.
Claims41
A fiber comprising:
- a fiber cladding material comprising a material selected from the group consisting of silica, a silicate, a borosilicate, and a phosphate glass, said fiber cladding material being disposed along a longitudinal-axis fiber length;
- and
- a plurality of discrete and disconnected high-stress domains disposed as a sequence along a longitudinal line parallel to the longitudinal fiber axis in at least a portion of the fiber length, each high stress domain having an internal pressure of at least 0.1 GPa and comprising a domain material that is interior to and different than the fiber cladding material.
A fiber comprising:
- a fiber cladding material, said fiber cladding material being disposed along a longitudinal-axis fiber length, said fiber cladding material having a softening temperature;
- and
- a plurality of discrete and disconnected high-stress domains disposed as a sequence along a longitudinal line parallel to the longitudinal fiber axis in at least a portion of the fiber length, each high stress domain having an internal pressure of at least 0.1 GPa and comprising a domain material that is interior to and different than the fiber cladding material, said domain material having a solidification temperature that is lower than said fiber cladding material softening temperature.
