US 4,726,648 A · Optoelectronic module

Abstract

An optoelectronic module is disclosed comprising an optoelectronic component (D), e.g. a photodiode (D) and/or a laser diode (D); a ring (RI) as an optical aperture in a wall of its housing (S/E/P, S/G/W) for the transmission of information-modulated light to or from the component (D) through the housing wall (S) to or from an optical component (L); and a lens system (K) having at least one lens (K), among them, at least one focusing lens (K) encircled by the ring (RI) or at least by a section of the ring (RI). At least one of the lenses (K) consists of glass and is intergrown with the ring (RI), at least in part consisting of glass, so as to be hermetically tight all around forming an intergrowth zone (SZ). Furthermore, the ring (RI) is inserted in the housing wall so as to form a hermetically tight seal.

Dependent claims

An optoelectronic module of an optoelectronic communiation system comprising

(a) an optoelectronic component;
(b) a ring for forming an optical aperture in a wall of a housing of the module for transmission of information-modulated light through the housing wall between said optoelectronic component and an optical transmission component;
and
(c) a lens system, including at least one focusing lens, encircled by the ring or at least by a section of the ring, for forming the interface between an electrical connecting line and the optical transmission component of said optoelectronic communication system, characterized in that said focusing lens (K), consisting of glass, is intergrown with the ring (RI), consisting at least in part of glass, hermetically tight all around, forming an intergrowth zone (SZ);
and the ring (RI) is inserted hermetically tight into the housing wall (W, S).
