摘要：
The authors demonstrate the first electron-transfer Mach-Zehnder modulators to operate in the 1.55mum wavelength range. The use of chopped quantum wells provides a wide operating bandwidth compatible with Er-doped fibre amplified systems (>40 nm about 1.54 mum) for electrorefractive waveguide devices. In this wavelength range, obtained voltage-length products are for the 180-degrees optical phase shift V(pi) x L between 2.7 and 4.0 Vmm.
