Abstract:
In a semiconductor device connected to a first optical waveguide, a phase modulation unit, and a second optical waveguide in this order and having an optical modulator guiding light in a first direction, the phase modulation unit includes: a semiconductor layer whose length in the first direction is larger than a width in a second direction orthogonal to the first direction and which is made of monocrystalline silicon; a core part serving as an optical waveguide region formed on the semiconductor layer, and extending in the first direction; a pair of slab parts arranged on both sides of the core part in the second direction; a first electrode coupled with one of the slab parts; and a second electrode coupled with the other of the slab parts. The core part has a p type semiconductor region and an n type semiconductor region extending in the first direction, and the second direction coincides with a crystal orientation <100> of the semiconductor layer.

Claim (Index 7):
The semiconductor device according to  claim 6 , further comprising a second insulating layer covering a main surface and a side wall of the semiconductor layer in the core part and main surfaces and side walls of the semiconductor layer in the first and second slab parts, and contacting with the first insulating layer,\n wherein a reflection index of the second insulating layer is lower than that of the semiconductor layer.
