Abstract :
The DFB-LD with a width-tapered waveguide lens is fabricated and narrow beam divergence property is realized. Excellent light output-current (L-l) characteristics in wide-temperature range and error-floor-free transmission at 622 Mbps-40 km are also confirmed. It is promising for the surface-mountable DFB-LD modules.
