Abstract
A method includes placing a fluid guide forming composition in contact with the optical source and with the optical fiber, injecting a first light in the guide forming composition from the optical source and/or from the optical fiber, to harden a central region of the optical guide, illuminating the guide forming composition with the second light to harden a peripheral region of the optical guide by photopolymerization initiated by the second photoinitiator system. The difference between the first peak wavelength and the second peak wavelength being more than 100 nm.
