ABSTRACT:
The waveguide-type optical device comprises a optical transmission element12, an optical waveguide20optically connected to the optical transmission element, and a slab optical waveguide30formed of an electrooptic material and optically connected to the optical waveguide20. In the waveguide-type optical device, a mode field width of the optical waveguide20has a value which is between a mode field width of the optical transmission element and a mode field width of the slab optical waveguide, whereby the connection loss between the optical transmission element12, such as an optical fiber, etc. and the slab optical waveguide30can be small.
