Component for optical data transmission

DETAILED DESCRIPTION The object of the invention is to provide an infrared transceiver having dimensions which are significantly smaller so that material costs and space requirements will be reduced.
According to the invention an optical infrared transceiver for a directed bi-directional optical data transmission combines the following features in a single-part or multi-part housing: an emitter chip for transmitting IR beams, a detector chip for receiving IR beams, a metallization between the chips, an integrated circuit for amplifying the transmission and reception power, an optical lens with an optical axis for focusing the transmitted and received beams, wherein the detector chip and the emitter chip are arranged one on top of the other and on the integrated circuit and concentrically to the optical axis of the optical lens thereby forming a stack.
The advantages of the invention are that it is possible to use a common optical lens for both, transmitter and receiver; this reduces the dimensions of the transceiver very considerably and provides savings in material costs.
In addition, shorter bond wires will reduce the interference sensitivity of the component.
Further advantageous applications of the invention are described below.
