A method is provided for manufacturing a lensed tip optical fiber. The method includes providing an optically transparent cylindrical fiber and etching a first end of the optically transparent cylindrical fiber to form a tip. The tip is heated which forms a lens surface at the heated tip. This lensed tip optical fiber makes optical alignment with other optical fibers and coupling of the optical fiber with photonic devices less burdensome.

L'invention concerne un procédé de fabrication d'une fibre optique à pointe présentant une lentille. Ledit procédé consiste à utiliser une fibre cylindrique optiquement transparente et à attaquer chimiquement une première extrémité de la fibre cylindrique optiquement transparente afin de former une pointe. La pointe est chauffée, une surface de lentille étant ainsi formée au niveau de la pointe chauffée. Ladite fibre optique à pointe présentant une lentille rend l'alignement optique avec d'autres fibres optiques et le couplage de la fibre optique avec des dispositifs photoniques moins coûteux.
