Abstract
A device for inserting a plurality of optical beams into a single-mode optical fibre, a guiding structure of which is composed of a core with a first refractive index, a cladding with a second refractive index, and a coating with a third refractive index. The device includes an optical mixer configured to insert, into the single-mode optical fibre, the plurality of optical beams, at least one of which has a distribution of its radial and angular electromagnetic amplitude with a maximum amplitude peak in the cladding.

An injecting method for injecting a plurality of optical beams into an output optical fiber, a guiding structure of which is composed of a core with a first refractive index, of a cladding with a second refractive index, and of a sheath with a third refractive index, wherein at least one of the optical beams has a distribution of its radial and angular electromagnetic amplitude with a maximum amplitude peak in the cladding, the method comprising:
- obtaining the plurality of optical beams, and
- injecting the optical beams by mixing into the output optical fiber.
