Abstract
A multi-stripe laser diode chip is integrated with a beam combiner on a single optical bench, and is thus, applicable to placement in a single pigtailed module. Specifically, multiple beams emitted from the chip stripes are spatially merged using a birefringent material and then coupled into an optical fiber. The use of the birefringent material provides an efficient solution for generating the merged beam, which can be coupled into a single optical fiber.
