Fiber draw synthesis process. The process includes arranging reactants in the solid state in proximate domains within a fiber preform. The preform is fluidized at a temperature below the melting temperature of the reactants. The fluidized preform is drawn into a fiber thereby bringing the reagents in the proximate domains into intimate contact with one another resulting in a chemical reaction between the reactants thereby synthesizing a compound within the fiber. The reactants may be dissolved or mixed in a host material within the preform. In a preferred embodiment, the reactants are selenium and zinc.

Photodetecting fiber. The fiber detects and localizes an incident optical beam. A semiconducting core is in intimate contact with a material forming a resistive channel that breaks axial symmetry. The resistive channel has a resistivity between that of metals and the semiconducting core, enabling the imposition of non-uniform, convex electric potential distributions along the fiber axis allowing photo-current measurements along the fiber.
