In this paper, an improved traveling wave electroabsorption modulators (TWEAM) waveguides with selectively undercut the active region is proposed and fabricated. Optical transmission on wavelength shows that the undercut-active-layer waveguide (UAW) structure has advantage over the conventional ridge-waveguide (CRW) due to the lower propagation loss and the difference (about 2 to 3 dB) between the UAW structures and CRW structures indicates that the optical insertion loss of UAW type is about 2 to 3 dB lower than the CRW. This kind of structure has high potential for the application of high-speed and lower optical insertion-loss EAMs.
