英文摘要 | PURPOSE:To generate two laser beams using one chip by arranging two electrodes interposing an impurity region between the two by a method wherein the stripe type impurity region to cross the center of a double hetero junction semiconductor layer and to demarcate a current passage having depth to reach a substrate is provided. CONSTITUTION:A current obstructing layer 5 and an active layer 6 to generate a laser oscillation are formed on a p type GaAs substrate 2, and the active layer 6 thereof is put between a first and a second clad layers 4, 7 having forbidden band gaps larger than the active layer 6 to form a double hetero junction semiconductor layer. A stripe type zinc diffusion region 20 to cross the center part of the semiconductor layer thereof and moreover having depth to reach the substrate 2 is provided, and electrodes 9, 9' are formed on both the sides of the region 20. A current 23 is made to flow toward the electrodes 9, 9' thereof to form laser beam emitting regions 21, 22 in the active layer 6 to enable to obtain two laser beams. The laser beam is outputted from the region 21 by applying a voltage to the electrode 9, and the laser beam is outputted from the region 22 when a voltage is applied to the electrode 9', and reliability of the device is enhanced. |
