Abstract
An laser/modulator assembly includes a laser source, such as a distributed feedback (DFB) laser, and a modulator, such as an electro-absorption modulator (EAM), integrated along a common waveguide. The waveguide has a distal end bent to define an inner side of the bent waveguide. A low reflectivity facet is arranged at the distal end of the waveguide, and a mirror is arranged at the inner side of the distal end of the waveguide to prevent any back reflection into the EAM waveguide from said low reflectivity facet, and the lateral trenches typically associated therewith.
