Abstract

Spiral patterned zinc oxide (ZnO) nanorods coated large core plastic optic fibers (POFs) improved optical side coupling efficiency from unpatterned continuous coatings. ZnO nanorods were grown by the hydrothermal method directly onto POF core. ZnO nanorods coating increased coupling inside the optical fiber by scattering light but were also capable of causing leakage. Structuring the growth of ZnO nanorod coating to specific regions permits light scattering from different segments along the fiber to contribute to the optimal coupled power. The best coupling voltage was found for the coating with growth time of 12 h and temperature of 90°C. Side coupling was improved to be a factor of 2.2 times better for spiral patterned coatings as opposed to unpatterned coatings.
