摘要： The disclosed tunable laser array may include multiple lasers including at least first and second lasers having center emission wavelengths that are separated by at least a specified minimum wavelength. The tunable laser array may also include at least one coupler/splitter. In the tunable laser array, emitted light from the first laser at a first wavelength and emitted light from the second laser at a second, different wavelength may be combined and then split at the coupler/splitter. Moreover, the lasers may have at least a minimum amount of thermal resistance. Various other systems, apparatuses, and methods of manufacturing are also disclosed.
