A method of mass-producing reliable, optical isolators, which allows reliable soldering and metallization in large quantities. The method comprise forming grooves (2) wider than a cutting margin along predetermined cut lines for cutting out a plurality of optical devices on the surface of an optical material block (1), forming then an antireflection film and a metallized film (3), and cutting the block along the grooves (2) ino optical elements (5).

Procédé de production de masse d'isolateurs optiques fiables, qui permet un brasage et une métallisation fiables en grandes quantités. Ce procédé consiste à former des rainures (2) plus larges qu'un bord de coupe le long de lignes de coupe prédéterminées afin de permettre la découpe d'une pluralité de dispositifs optiques dans la surface d'un bloc de matériau optique (1), et à former ensuite un film antireflet et un film métallisé (3) avant de découper le bloc le long des rainures (2) pour former des éléments optiques (5).
