Monolithic optical system and method of making same including improved coupling means between an optical fiber and a phototransducer

摘要

An optical system comprising a monomode main optical fiber coupled to a phototransducer, by means of an assembly between the monomode optical fiber and the phototransducer, which assembly comprises, in succession: a piece of graded index multimode fiber, a piece of step index multimode fiber, and a microlens.
