Abstract
A systematic experimental study is presented on the waveguide width effect on the highspeed electrical and electro-optical (EO) response of the traveling wave co-planar waveguide Mach-Zehnder modulators (MZMs). Modulators with waveguide widths from 1 to 1.5 μm fabricated in a generic InP platform are measured. Electrical peak reflection of the 50W terminated modulators shows that waveguide width reduction improves the impedance matching. Modulators with narrower waveguides also offer higher electrical bandwidth and velocity matching. Moreover, the electro-optical frequency response of the MZMs shows 47% bandwidth improvement from 36 GHz in a modulator with 1.5 μm waveguide width to 53 GHz with 1 μm width.
