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 1):
An optical waveguide element, comprising:\n a rib waveguide, serving as a core section, which includes (i) a rib region having a first height and (ii) two slab regions located such that the rib region is sandwiched, in a first direction, between the two slab regions, each of the two slab regions having a second height which is lower than the first height, the core section including a first core region and a second core region which are located so as to overlap each other in a second direction which is perpendicular to the first direction, the first core region and the second core region forming a PN junction, a depletion layer being formed between the first core region and the second core region, the depletion layer extending from the rib region to both of the two slab regions, the depletion layer being located so as to be lower, in the second direction, in each of the two slab regions than in the rib region, the rib region having a width, as measured at a location of the second height, which is wider than a width as measured at a location of the first height.
