Abstract

An optoelectric module for bidirectional optical data transmission has a molded element provided as a beam splitter, which consists essentially of a material that is transparent for the emitted radiation and the received radiation, and in which a beam splitter is embedded. A transmitting component, a receiving component and a radiation focusing device are advantageously directly connected to the molded element.

Dependent claims

An optoelectronic module for bidirectional optical data transmission, comprising:

a transmitting component with a beam output surface for emitting radiation;
a receiving component with a beam input surface for receiving radiation;
a beam splitter with a beam splitter layer and a radiation focusing device having a beam input and beam output surface, said beam splitter being a molded element consisting essentially of a material transparent to emitted radiation emitted by said transmitting component and to received radiation to be received in said receiving component, and said beam splitter layer being embedded in said molded element so as to intersect a beam axis defined by the emitted radiation and a beam axis defined by the received radiation;
said molded element having a first side surface, a second side surface inclined relative to said first side surface, and a third side surface inclined relative to one of said first side surface and said second side surface;
said molded element having mutually opposite side surfaces formed by said first side surface and said third side surface or said second side surface and said third side surface, respectively;
said beam output surface of said transmitting component facing and being connected to said first side surface, said beam input surface of said receiving component facing and being connected to said second side surface, and said beam input and beam output surface of said radiation focusing device facing and being connected to said third side surface;
and
said transmitting component, said receiving component, said beam splitter and said focusing device being arranged relative to one another, so as to enable the optoelectronic module, during an operation thereof, to output at least a portion of the emitted radiation to an optical device optically coupled to the optoelectronic module, and at least a portion of the received radiation to be input from the optical device and into said receiving component.
