A frequency multiplexing light source is realized by monolithically integrating GaAs-GaAlAs distributed-feedback diode lasers with different grating periods and passive waveguides on a GaAs substrate. The lasers with wavelength separation of approx.20 A are modulated independently, and the output beams are obtained from a common launching waveguide. (AIP)
