Abstract
The authors demonstrate the first electron-transfer Mach-Zehnder modulators to operate in the 1.55 µm wavelength range. The use of chopped quantum wells provides a wide operating bandwidth compatible with Er-doped fibre amplified systems (>40 nm about l.54 µm) for electrorefractive waveguide devices. In this wavelength range, voltage–length products obtained are for the 180° optical phase shift Vπ×L between 2.7 and 4.0 Vmm.Keywords
