Abstract
The techniques which allow the stimulated photon echo to be used for digital addition are proposed. Time encoding is used to represent the input multibit numbers by laser pulse sequences. The on- and off-bits are encoded by the pulse intensities. The implementation of the logical operations AND, OR, XOR, and EQV is fulfilled in one setup. The setup includes an interferometer of the Mach-Zehnder type. To process the different bits in parallel a technique of frequency scanning within specimen inhomogeneous linewidth is invoked. Various adders are considered. An operation of both the half adder and full adder devices is based on cyclic repetition of the procedures SUM and CARRY. A carry-free adder with time data encoding based on the residue arithmetic is also considered.
