Abstract: A fiber attachment structure may comprise a monolithic platform structure having a first trench and a second trench to segment the monolithic platform structure into a chip mount area, a first island, and a second island. A laser chip may be mounted directly on the chip mount area and an optical fiber may be mounted on the first island by a first adhesive joint and on the second island by a second adhesive joint. For example, in some implementations, the first adhesive joint may include a first quantity of adhesive material attaching the optical fiber to the first island at a position at which a tip of the optical fiber is aligned with an output facet of the laser chip, and the second adhesive joint may include a second quantity of the adhesive material to mechanically secure the optical fiber to the second island.
