1. A planar integrated opto-electronic transceiver apparatus comprising in combination:
- a first silicon on sapphire substrate with a first tapered slot line antenna deposited on the surface of the silicon epilayer, said first slot line antenna having a narrow slot at one end and a large aperture at its other end, said first slot line antenna having a predetermined overall length, said first slot li-ne antenna receiving a DC bias, said first slot line antenna receiving an optical pulse signal at said narrow slot which causes an electromagnetic transient to propagate down said first slot line antenna towards its aperture, said electromagnetic transient is radiated from said aperture of said first slot line antenna, and,a second silicon on sapphire substrate with a second tapered slot line antenna deposited on the surface of the silicon epilayer, said second slot line antenna having a narrow slot at one end and a large aperture at its other end, said second slot line antenna having a predetermined overall length, said second slot line antenna receiving a DC bias, said second slot line antenna receiving said electromagnetic transient at said aperture of said second slot antenna, said electromagnetic transient is propagated down said second slot line antenna towards said narrow slot, said electromagnetic transient is detected and time resolved at said narrow slot by a photoconductive signal which is applied to said narrow slot.

Abstract
A planar integrated opto-electronic transceiver apparatus having a pair of broadband tapered slot line antennas which are monolithically integrated on an ion implanted silicon on sapphire substrate. An optical pulse which is applied to the narrow slot of the transmitting antenna, generates an electromagnetic transient to the antenna aperture from which it is radiated to receiver slot line antenna. The received electromagnetic transient is detected at the narrow slot and is time resolved by an optical sampling signal.
