Abstract:
1. A method for manufacturing an optical fiber comprising: heating an end of a crystal material to melt, and drawing the molten end of the crystal material to form a crystal filament, with the crystal filament including an outer periphery having a first surface section and a second surface section spaced from the first surface section along a longitudinal plane of the crystal filament; coating conductive paint on the first and second surface sections of the crystal filament to form an internal positive electrode and an internal negative electrode not electrically connected to the positive negative electrode; placing the crystal filament with the internal positive and negative electrodes into a heat resistant tube, and heating the heat resistant tube until an outer layer of the crystal filament melts and adheres to an inner periphery of the heat resistant tube, with a center of the crystal filament remaining as a solid core; and adhering conductive paint to two ends of the crystal filament to form an external positive electrode and an external negative electrode electrically connected to the internal positive electrode and the internal negative electrode, respectively.
