Abstract

A tunable multiwavelength laser source is required for many applications, e.g., wavelength-division multiplexing (WDM), two- wavelength interferometry, differential lidar and optical data storage. Recent efforts in this field have been directed toward the use of diode array with individual addressable diodes1-4 for achieving simultaneous multichannel operation. In the multichannel grating cavity (MCG)1 laser or multistripe array grating integrated cavity (MAGIC)2 laser, several array ridges were pumped separately to generate output at different wavelengths. For either scheme, injection pumping of selected stripes requires elaborate fabrication and packaging procedures.
