Abstract
By utilizing two electrodes on a conventional uniform-grating distributed feedback (DFB) injection laser, the usual two-mode DFB laser degeneracy has been removed to permit (1) single-frequency operation with 33-dB side-mode suppression and (2) current-controlled switching between the two modes, separated by a 10-25 Å stop band, in less than 1 ns.
