Flat electrooptical component for sending and receiving electrical and optical signals has central emission area, sensor area, reflector area, control and signal output arrangements

摘要

The device has a central emission area (100) with at least one light emitting device (102) for sending optical signals, a sensor area (110) round the emission area with at least one optical signal receiving device, a reflector area (120) around the emission area for reflecting incident electromagnetic radiation and arrangements for controlling the light emitting device and outputting electrical signals on the basis of incoming electrical signals. Independent claims are also included for a light conductor arrangement and an optical circuit board.
