Abstract
An integrated, single output port, tunable multiple wavelength laser apparatus produces one of N N wavelengths using only N plus N selection signals. Each of N ports can output N of the laser wavelengths, the port being selected by the N control signals and the particular one of the N wavelengths being selected by the N control signal. An N ×1 router combines the signals from the N output ports into a single output.
