<p>An optoelectronic apparatus where information is communicated to and from the apparatus in the optical domain, but where the apparatus includes a transmission gate (151) interposed between successive optoelectronic gates (101, 102) to sequentially convey information internally in the form of electrical, rather than optical, signals. Illustratively, the transmission gate is optoelectronic and comprises two back to back p-i-n photodiodes each including a quantum well region. The first and second optoelectronic gates are S-SEEDs comprising p-i-n photodiodes also each including a quantum well region. The transmission gate is responsive to a first level of an optical control signal ( 109, 119) for substantially blocking current, and to a second level of the optical control signal for substantially passing current. Applicarions of the apparatus include its use in a shift register, 2 x 1 switch, 1 x 2 switch, and an exclusive OR gate. <IMAGE></p> |
