Abstract
A semiconductor optical integrated element includes: a substrate; and a laser diode and a modulator which are integrated on the substrate. The laser diode includes an embedded waveguide having a core layer, both sides of which are embedded in a semiconductor material. The modulator includes a high-mesa ridge waveguide having a core layer, neither side of which is embedded in the semiconductor material. The core layers in the laser diode and the modulator are stripe-shaped.
