Abstract
The invention relates to an emitter-receiver semiconductor diode device for direct optical coupling to optical signal transmission apparatus. It is a unitary combination of a double heterostructure diode and a waveguide photodiode with elements to selectively switch between an emission mode and a receiving mode. Confining semiconductor at least partially restrict light to junction-forming active and waveguiding semiconductors of the diode.
