Hybrid Photonic-integrated Electroabsorption Optical Vector Modulator for 80G/100G Applications

We review recent developments of novel hybrid photonic-integrated devices consisting of AlGaInAs/InP electroabsorption modulators and a four-arm silica-on-silicon planar lightwave circuit optical interferometer. The device is format-agile and capable of generating various optical modulation formats, including spectrally-efficient formats such as Quadrature-Phase-Shift-Keying. We discuss the device technology platform and the device applications to 80/100 Gb/s optical transmission.
