| abstract | PROBLEM TO BE SOLVED: To provide a semiconductor optical device having a structure capable of suppressing deterioration of energization characteristics by suppressing diffusion of a p-type dopant into a light emitting layer on an end face of a semiconductor mesa portion. A semiconductor optical device 1 includes a semiconductor mesa portion M including a light emitting layer 23 and a p-type cladding layer 25, and a p-type buried region 13. The semiconductor mesa portion M includes a first mesa region Ma and a first mesa region Ma. There are second mesa regions Mb and Mc, and the first mesa region Ma is located between the second mesa regions Mb and Mc. p-type cladding layer 25 has a first portion 25 1 of the first mesa region Ma, second mesa region Mb, and a second portion 25 2 in Mc. p-type buried region 13 has a first portion 13 1 of the side surface of the first mesa region Ma, second mesa region Mb, and a second portion 13 2 on the side of Mc. In one of the p-type cladding layer 25 and the p-type buried region 13, the concentration of the p-type dopant in the second portion is lower than the concentration of the p-type dopant in the first portion.
