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.

L'invention concerne un procédé de fabrication d'un guide d'onde optique de biopolymère qui comprend la fourniture d'un biopolymère, le déroulement du biopolymère progressivement pour extraire des fibres de biopolymère individuelles et le placement des fibres déroulées sous tension mécanique. Les fibres mises sous tension mécanique sont ensuite coulées dans un polymère différent pour former un guide d'onde optique de biopolymère qui guide la lumière en raison de la différence d'indices de réfraction entre le biopolymère et le polymère différent. Les fibres optiques peuvent être utilisées dans des applications biomédicales et peuvent être insérées dans le corps en tant que milieux transmissifs. Des techniques d'impression peuvent être utilisées pour fabriquer les guides d'ondes optiques de biopolymère.
