Abstract

Device for communication by light, including means for transforming electrical signals to light signals, a transmitter for emitting said light signals, a combined light sensitive means and transforming means (10) for transforming said light signals to elecrical signals, a diode (9) being provided as a light sensitive means, and means being provided for supplying a backward biasing current to said diode. Said diode (9) is arranged in series with a first transistor (T1) in a current mirror coupling for providing a mirror of the current through said diode (9) in a second transistor (T2) of said current mirror coupling, an output of said electrical signals being provided across said second transistor (T2).
