<p>A method of mass-producing reliable, optical isolators, which allows reliable soldering and metallization in large quantities. The method comprises 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). <IMAGE></p> |
