Abstract:
An optical transmitter-receiver module comprising:an electrically conductive platform substrate having a transmitter region and a receiver region; a first insulating film extending over said transmitter region and said receiver region of said electrically conductive platform substrate; a first electrically conductive layer having a first fixed-potential, and said first electrically conductive layer extending in said receiver region and over said first insulating film; a second insulating film selectively extending over said first electrically conductive layer; an optical receiver circuit including at least a light-receiving device, and said optical receiver circuit existing over said second insulating film; an optical transmitter circuit including at least a light-emitting device, said optical transmitter circuit existing in said transmitter region, and said light-emitting device existing on said first insulating film; and a first electrically conductive shielding member spatially isolating said optical receiver circuit from said optical transmitter circuit, and said first electrically conductive shielding member being electrically coupled to said first electrically conductive layer, so that said first electrically conductive shielding member has said first fixed-potential.
