System and method for fabricating multiplexable active optical fiber sensors

A system for manufacturing an optical fiber sensing device, comprising:

• a fiber translation device structured and configured for moving an optical fiber having a core linearly along a first direction;
• an ultrafast laser system structured and configured to generate and output a laser beam;
• a beam focusing system coupled to the ultrafast laser system, the beam focusing system being structured and configured to focus the laser beam into the core while the optical fiber is being moved linearly by the fiber translation device to enable direct writing of a number of nanograting structures into the core using the laser beam, wherein the number of nanograting structures form a number of scattering points;
• and
• a coating device structured and configured to form an energy transducing element on an outer surface of the optical fiber by coating the outer surface with one or more materials, wherein the number of scattering points is/are structured and configured to scatter light out of fiber core and into the transducing element to provide local power for the optical fiber sensing device.
