Abstract
The present disclosure relates to a method for manufacturing end microlenses of individual optical fibers which are part of a bundle or a multi-core fiber, including depositing a drop of a photopolymerizable solution on a first end of the bundle; adapting the size of the drop; applying light centered on a predetermined wavelength onto a second end of the bundle in order to selectively polymerize the drop; rinsing the first end using a methanol solution in order to obtain a network of individual optical fibers, each one of which is provided with a microlens at the first end of the multi-core fiber, the microlenses being physically separated from one another. The disclosure additionally relates to a bundle of microlensed fibers obtained by the method, as well as to the use of such a bundle, for example in medical or multiplexed imaging and/or in the coupling of optical fibers.
