Abstract
A method of manufacturing a biopolymer optical waveguide includes providing a biopolymer, unwinding the biopolymer progressively to extract individual biopolymer fibers, and putting the unwound fibers under tension. The tensioned fibers are then cast in a different polymer to form a biopolymer optical waveguide that guides light due to the difference in indices of refraction between the biopolymer and the different polymer. The optical fibers may be used in biomedical applications and can be inserted in the body as transmissive media. Printing techniques may be used to manufacture the biopolymer optical waveguides.
