Abstract

By splitting the electrical contact of a conventional distributed feedback (DFB) laser into two sections, the frequency tuning characteristics of the DFB laser are modified and the DFB two-mode degeneracy becomes electrically controllable. As a result, novel device functions can be achieved. Several applications of two-electrode DFB lasers are described: (1) active single-mode stablization, (2) control of spectral reliability and wavelength chirp under amplitude modulation, (3) logic gate operations utilizing the DFB two-mode degeneracy for switching, routing, and optical computing, and (4) frequency modulation of the DFB laser for FSK coherent communication systems and optical sensing.
