The objective of the combined Phase I/Phase II research program is to develop a method of manufacturing low-cost laser diode products in which efficient, high-brightness laser coupling is achieved using integrated optical components formed on a silicon substrate. In Phase I of this program, the first successful application of a new process to fabricate such integrated optical components was demonstrated. These components were used to achieve high brightness coupling of lasers to multimode fibers. High coupling efficiency was also achieved. A laser array was passively aligned and bonded to a common silicon substrate. In Phase II, the development of a single mode fiber coupled laser diode package in which the laser and fiber are bonded to a silicon bench with integrated coupling is proposed. The development of two additional devices is also proposed as an option. Development of microbench technology will offer a significant opportunity to reduce the cost of manufacturing fiber coupled laser diode products for communications, computing, laser printing, optical data storage, and remote sensing.
