Abstract
To reduce the optical loss, lower the driving voltage, produce a smaller product, and simplify the production process, an embodiment of the present invention includes a rib waveguide core (101) having a rib region (101r) and two slab regions (101s), where a depletion layer (113) is so formed as to extend from the rib region (101r) to the two slab regions (101s).
