  • Laser diode array and manufacturing method thereof
    Patent number: 5163064
    Abstract: The present invention relates a laser diode array and its manufacturing method. After formation of V-channels on an N-type GaAs substrate, each layer is formed by molecular beam epitaxy technique. By using that Si acts as P-type dopant on {111} A surface of V-channel, while acting as N-type dopant on {100} surface of the outside of V-channel, a laser array structure is improved. Thus, the present invention is useful in obtaining stable optical output efficiency and mode control, yield improvement, reproducibility, and high output laser beam.
