We describe several experiments which use a picosecond pump-and-probe technique to perform optical logic operations in GaAs etalons [1, 2]. An operating cycle time of less than 70 ps is demonstrated in a thin “windowless” bulk GaAs device by successive operations. Arrays of NOR gates up to 2 × 4 in size are obtained by optically contacting a multiple-quantum-well (MQW) structure between reasonably flat mirrors. We also demonstrate an “optical data diode” through which data can flow efficiently in only one direction.
