Abstract
An optical fiber (1′) having at least one Bragg grating (11), the fiber comprising a core (2) surrounded successively by cladding (3) and by a coating (4), the grating being obtained by being written directly in the core and/or the cladding of the fiber through the coating which is made of a material that is substantially transparent to ultraviolet type radiation used for writing the grating, and wherein the material of the coating contains a first polymer network interpenetrated by a second polymer.
Claims18
An optical fiber having at least one Bragg grating, the fiber comprising a core surrounded successively by cladding and by a coating, said fiber being obtained by directly writing said grating in the core or the cladding through the coating which is made of a material that is substantially transparent to the ultraviolet radiation used for writing said grating, in which the material of said coating contains a first polymer network interpenetrated by a second polymer.
An optical device incorporating a fiber having a Bragg grating, the fiber comprising a core surrounded successively by cladding and by a coating, said grating being obtained by being written directly in the core or the cladding of the fiber through the coating which is made of a material that is substantially transparent to ultraviolet radiation used for lighting said grating, wherein the material of said coating contains a first polymer network interpenetrated with a second polymer.
An optical fiber, comprising:
- a core;
- a cladding surrounding the core;
- a coating surrounding the cladding;
- and
- at least one Bragg grating;
- wherein the coating comprises a material that is substantially transparent to the ultraviolet radiation, the material comprising a first polymer network interpenetrated by a second polymer network.
