A carrier (1) for treating photonic devices such as laser bars (B) is provided with a recessed formation (3) with a web surface (3a) for supporting the photonic device in contact therewith as well as at least one side surface (3b) forming an abutment surface for engaging a respective end facet (S1, S2) of the photonic device. The photonic device (B) is arranged in the recessed formation (3) so that the lower surface (LB) of the photonic device is masked with respect to the treatment source, while at least one end facet (S1, S2) of the photonic device engages at least one side surface (3b) by leaving exposed a surface to be treated. A protection member (5) is placed in contact with the upper surface (UB) of the photonic device (B) and the carrier (1) with the photonic device (B) arranged therein is exposed to the treatment source (E). The treatment is thus effective substantially exclusively on the surfaces of the end facets (S1, S2) to be treated.
