Abstract

L'invention concerne les dispositifs optiques à semiconducteurs. Les facettes d'émission de lumière d'une diode laser au GaAs sont munies de revêtements 4, en verre au silicate de plomb. On peut choisir la composition de ce verre de façon à définir le pouvoir réfléchissant des facettes, et à obtenir une bonne correspondance entre le coefficient de dilatation du substrat 1, et celui du revêtement Les revêtements 4 protègent en outre le dispositif contre l'action de l'atmosphère. Application aux télécommunications optiques.
