A low-cost and high-performance 4-λ wavelength division multiplexing distributed feedback (WDM-DFB) laser array (or WDM4), employing a newly developed asymmetric strongly gain-coupled (A-SGC) laser structure, and a novel compact packaging approach was developed for optical network applications. The WDM4 laser array is capable of simultaneous 4-λ 100 km transmission through a standard nondispersion-shifted fiber, with a simultaneous and independent direct modulation at 2.5 Gb/s for each of the four WDM channels spaced by 200 GHz
