Abstract
A semiconductor optical device may include a semiconductor substrate; a compound semiconductor layer on the semiconductor substrate; an additional insulating film on the pedestal portion of the compound semiconductor layer, the additional insulating film having an upper surface and a side surface at an inner obtuse angle between them; a passivation film covering the compound semiconductor layer and the additional insulating film except at least part of the mesa portion, the passivation film having a protrusion raised by overlapping with the additional insulating film; a mesa electrode on the at least part of the mesa portion; a pad electrode on the passivation film within the protrusion; and an extraction electrode on the passivation film, the extraction electrode being continuous within and outside the protrusion, the extraction electrode connecting the pad electrode and the mesa electrode, the extraction electrode being narrower in width than the pad electrode.
