Abstract
A device for coupling optical fibers, includes a first coupling-inhibited hollow-core optical fiber comprising a first microstructured cladding comprising a plurality of first confining tubular features distributed in a ring and encircling, at least partially, a first core so as to confine at least radiation at a wavelength λop to the first core, a second coupling-inhibited hollow-core optical fiber comprising a second microstructured cladding comprising a plurality of second confining tubular features distributed in a ring and encircling, at least partially, a second core so as to confine the light radiation to the second core, a coupling element arranged between the first and second cores, the coupling element comprising at least one coupling tubular feature comprised at least partially in the first microstructured cladding and/or the second microstructured cladding and having a wall thickness tcp called the coupling thickness and a material index ncp called the coupling index, an arrangement of the coupling element, the coupling thickness tcp and the coupling index ncp being configured so as to create a leakage channel at the wavelength λop allowing the radiation guided by the first optical fiber to be coupled to the second optical fiber and/or the radiation guided by the second optical fiber to be coupled to the first optical fiber.
