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 diodes^1-4 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.
