Abstract: (1098 Views)
Implanting optical fiber into tissue is one of the ways to deliver light and overcome the issue of tissue turbidity. In this paper, the design and fabrication of a new type of a polymer optical fiber with flexible and degradable biocompatible step-index for the delivery of light with a diameter of 1400µm and lengths of 3 cm and 7 cm are presented. The degradation rate of the optical fiber polymers poly (octamethylene maleate citrate) and poly (octamethylene citrate) for 10 days is -1.5 mg/day and -1.8 mg/day, respectively. By coupling the light with the microsphere lens into the optical fiber structure and also by using the new chemical abrasion method of the optical fiber tip, obtained output power efficiencies at 532 nm, 589 nm and 650 nm are 77.8%, 30% and 24.2%, respectively. The flexibility and degradability of polymer optical fiber reduce and eliminate the constraints created by fiberglass, including restricting the animal’s free movement, fragility, and tissue damage from leaving the tissue.
