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 9):
The optical waveguide element as set forth in  claim 1 , wherein:\n the optical waveguide element includes a first tapered section and a second tapered section,\n the first tapered section having a tapered shape such that the two slab regions each have a width in the first direction, the width becoming smaller as a distance from one of a light-entering end and a light-exiting end of the first tapered section decreases, \n a second tapered section being located so as to be adjacent to the other of the light-entering end and the light-exiting end of the first tapered section, the second tapered section having a tapered shape such that a width, in the first direction, of the rib region becomes smaller as a distance from one of a light-entering end and a light-exiting end of the second tapered section decreases.
