电吸收调制器。调制器包括SOI波导；有源区，所述有源区包括多量子阱（MQW）区；以及耦合器，用于将SOI波导耦合到有源区。耦合器包括：过渡波导耦合区；缓冲波导耦合区；以及锥形区；其中，过渡波导耦合区耦合SOI波导与缓冲波导耦合区之间的光；以及缓冲波导耦合区经由锥形区耦合过渡波导区与有源区之间的光。 An electroabsorption modulator. The modulator comprising an SOI waveguide; an active region, the active region comprising a multiple quantum well (MQW) region; and a coupler for coupling the SOI waveguide to the active region. The coupler comprising: a transit waveguide coupling region; a buffer waveguide coupling region; and a taper region; wherein, the transit waveguide coupling region couples light between the SOI waveguide and the buffer waveguide coupling region; and the buffer waveguide coupling region couples light between the transit waveguide region and the active region via the taper region.
