Abstract:
Provided is an optical waveguide element having a reduced optical loss, a lower driving voltage, and a reduced size. A rib waveguide core of an optical waveguide includes a first core region and a second core region which constitute a PN junction and which are provided so as to overlap each other in a horizontal direction. A depletion layer is formed between the first core region and the second core region. The depletion layer extends from a rib region to both of two slab regions. The depletion layer is located so as to be vertically lower in the slab regions than in the rib region.

Claim (Index 4):
The optical waveguide element as set forth in  claim 1 , wherein:\n the rib region has sidewalls each of which is inclined at an angle of not smaller than 45 degrees and not greater than 80 degrees.
