More Information
Summary:A laser source assembly is based upon an optical reference substrate that is utilized as a common optical reference plane upon which both a fiber array and a laser diode array are disposed and positioned to provide alignment between the components. Passive optical components used to provide alignment between the laser diode array and the fiber array are also located on the optical reference substrate. A top surface of the reference substrate is patterned to include alignment fiducials and bond locations for the fiber array receiving block, laser diode array submount and passive optical components. The receiving block is configured to present the optical fibers at a height that facilitates alignment with the output beams from the laser diodes positioned on the silicon submount.
