Abstract
An electro-absorption modulated laser is provided having three sections, a laser section, an isolation section, and a modulation section. The laser section produces light along a straight waveguide path. The modulation section also has a straight waveguide path, but is angled with respect to the laser section's path. The isolation section between the other two sections includes a path that is collinear with the respective laser or modulation section at each end, but is gradually curved in the middle.
