Optoelectronic device with independent light emitting element - has semiconductor PN junction and light emitting surface

摘要

The light emitting surface emits a specific light signal in accordance with an electric signal applied to the SC element. It has a first integrated circuit (13, 14) in an Sc wafer (40) which applies the electric signal to the light emitting element. A light receiving SC component is produced in the SC wafer. It receives the light emitted by the light emitting element, and converts it by its p-n junction into an electric signal. A second circuit (41-45) is produced on the SC wafer (40). It delivers an output signal in accordance with electric signal from the light receiving component. The light emitting element and the first circuit (113, 114) are insulated from the light receiving component (1) and the second circuit (41-45). The light emitting element has a pair of connections (21-29) to which the first circuit (113, 114) is connected.
