Spectroscopic measurement with cellulose optical fiber

Research output: Contribution to conferenceConference AbstractScientific


Cellulose is a new promising candidate for biodegradable optical fiber material for sensing applications. Cellulose-based optical fibers have features like fast wetting and drying that commercial glass optical fiber and polymer optical fibers does not have. We have recently demonstrated three different types of fibers viz., regenerated cellulose, methylcellulose and carboxymethyl cellulose. These fibers have attenuations in the range of 1.5-6 dB/cm, the transmission spectrum between 500-1400 nm and diameter 300 μm. More importantly, it is possible to transmit 150 Mbit/s signals using a few centimeters of fibers. The optical performances have been tested in water, humidity, touch, and respiratory rate applications.
