Summary:Embodiments of the present disclosure describe techniques and configurations for decreasing optical loss in a waveguide of a modulator device. In one embodiment, an apparatus includes a substrate, and a waveguide of a modulator device formed on the substrate, the waveguide having a first portion that is configured to receive light for propagation along the waveguide, a second portion that includes two slots formed in the waveguide that merge into a single slot, the second portion being coupled with the first portion, a third portion that includes the single slot formed in the waveguide, the third portion being coupled with the second portion, a fourth portion that includes another two slots formed in the waveguide, the another two slots branching from the single slot, the fourth portion being coupled with the third portion, and a fifth portion that is configured to output the propagated light, the fifth portion being coupled with the fourth portion. Other embodiments may be described and/or claimed.
