| 英文摘要 | PURPOSE:To reduce the unstability of photooutput by a method wherein the width of a narrow stripe region of a semiconductor laser element which has a P type impurity region in the other region except for the above-mentioned stripe region is formed at a value less than a specific value. CONSTITUTION:A P type clad layer 2, an N type, P type or undoped laser active layer 3, and an N type clad layer 4 are formed on a P type semiconductor substrate Further, a cap layer 5 is formed. Next, an impurity diffused region 6 is formed by diffusing a P type impurity in the other region except for the narrow stripe region. It is contrived that the width of the stripe region 10 wherein the above-mentioned P type impurity is not diffused becomes less than 5.0mum. The region 6 is reversely biased when a normal bias voltage is impressed. Therefore, current is brought into stricture efficiently to the region 10 wherein the P type impurity is not diffused, and accordingly a semiconductor laser element having the distribution of gain in a narrow region can be obtained. |
