Abstract
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 ∼20 Å are modulated independently, and the output beams are obtained from a common launching waveguide.Keywords
