ABSTRACT:
A technique is described for creating a localized modulation of an optical fiber's refractive index profile. A segment of optical fiber is loaded into a heating unit having a resistive heating element with a localized heating zone. A selected portion of the fiber segment is positioned within the heating zone, and the heating unit is used to create a refractive index modulation the selected fiber portion. The localized modulation is repeated along the length of the fiber segment to write a fiber grating. Also described is a resistive heating system for performing the described technique.
