Abstract

Cellulose materials offer new biodegradable alternatives for fabricating optical fibers for sensing applications. Unlike glass and polymer optical fibers, these environmentally friendly materials have intrinsic properties making them attractive candidates for functional optical fibers. Cellulose fibers are hygroscopic and thus can rapidly take water vapors from the surroundings and dry quickly. Cellulose-based optical fibers can be manufactured from regenerated cellulose or cellulose derivatives which offer a large property space. They can be resistant or soluble in water, and the refracting index of the material can be tuned as needed. In this work, feasibility for sensor applications of three different cellulose optical fibers have been tested: regenerated cellulose for water and humidity sensing, carboxymethyl cellulose for respiratory rate monitoring, and methylcellulose for short-range 150 Mbit/s signal transmission at 1310 nm. Therefore, fast signal transmission can be achieved with short cellulose-based sensor fibers. The work shows the scientific and technical potential of a novel optical material for photonics.
