Abstract

Recently, we demonstrated utilization of the two-mode degeneracy property1 of distributed feedback (DFB) injection lasers for high-speed electrooptical switching.2 This paper reports electrooptical logic operations using a two-electrode DFB laser at a 1.3-μm wavelength. A complete set of AND, NAND, OR, NOR, and INVERT logic gates was demonstrated by detecting the output light of one of the two degenerate modes that were switched by electrical signals applied to the two electrodes.
