英文摘要 | PURPOSE:To improve the light detection efficiency by forming the light emitting side end surface of a light detecting part so as to form a Brewster's angle with a laser beam entering the light detecting part. CONSTITUTION:A lower cladding layer 6, an active layer 7, an upper cladding layer 8, buried layers 9 and 10 for current blocking and ohmic electrodes 1-3 are formed on a substrate 5. A separation trench reaching the lower cladding layer 6 is formed to separate a light emitting part from a light detecting part. The end surface 4 of the light detecting part is so formed as to form a Brewster's angle alphaB with an incident laser beam, thus making the reflectance at the end surface 4 zero. With this constitution, the light detection efficiency can be improved so that the deterioration of the light emitting characteristics can be suppressed. |
