Optical modulator and package
An optical modulator includes a dielectric layer and a waveguide. The waveguide is disposed on the dielectric layer. The waveguide has a first region, a second region, and an optical coupling region between the first region and the second region. The waveguide located in the first region includes a first electrical coupling portion and a first slab portion connected to each other. The waveguide located in the second region includes a second electrical coupling portion and a second slab portion connected to each other. The waveguide located in the optical coupling region includes a first optical coupling portion and a second optical coupling portion. The first slab portion has at least two sub-portions having different heights. The second slab portion has at least two sub-portions having different heights.
