A solid state optoelectronic switching and display device and a method for its manufacture are disclosed. The device, formed in silicon, essentially is a surface-emitting visible light-emitting diode that allows rapid and efficient switching and information transfer, via optical means, between IC's, PC boards and displays in a computer. The method essentially includes electrochemically etching a silicon wafer to form a porous silicon region therein, depositing a transparent semiconductor layer on the porous silicon region, and forming a back contact on the wafer.
