英文摘要 | PURPOSE:To improve basic characteristics such as threshold current value, operating current value and to enhance the output of a semiconductor laser by reducing the thickness of a semiconductor active layer disposed within a predetermined range from the end face of a semiconductor laser along a stripe smaller than that of the active layer of a stripe except it. CONSTITUTION:An etching mask 11 which covers a region except a region having 4mum of width of a portion of 20mum or larger from the end face and 8mum of width of the portion except the region is formed on a semiconductor substrate The portion from the mask 11 is etched, a channel 12 is formed, and the mask 11 is removed. A semiconductor light enclosing layer 2, a semiconductor active layer 3, a semiconductor light enclosing layer 4, and a semiconductor cap layer 5 are sequentially formed by a liquid epitaxial technique on the substrate Then, a contact region 6 is formed to the depth which arrives at part of the layer 4 from the surface of the layer 5 by diffusing technique. Electrodes 7 are formed on the layer 5 including the region 6 and the back surface of the substrate 1 to obtain a semiconductor laser. |
