ABSTRACT:
An optical parallel-to-serial converter constructed from at least two optical shift registers coupled in cascade by an optical two-to-one combiner. The input port of the first optical shift register serves as one input to the parallel-to-serial converter, an extra optical combiner optically coupled to the last of said optical shift registers serves as one input port, while the optical combiners coupling said optical shift registers serve as the other input ports receiving parallel optical pulses. The output port of the last of said cascaded optical shift registers serves as the output port of the parallel-to-serial converter. The shift registers are controlled by two clocks, operating at the same rate, but each out of phase with the other, providing control signals to shift and output said optical pulses serially from said shift registers to effect a parallel-to-serial conversion.
