Abstract

Two or more of striped structures are formed in one chip, and a relaxation oscillation frequency of the first striped structure is greater than a relaxation oscillation frequency of the second striped structure. An RIN value at low output is improved by the first striped structure having a higher relaxation oscillation frequency, and a single transverse mode and reliability at high output are obtained by the second striped structure having a lower relaxation oscillation frequency.
