Abstract :
A new type of resonant optical intensity modulator has been developed by incorporating an optical slow-wave structure into a GaAs/AlGaAs Mach-Zehnder waveguide modulator. The first experimental results demonstrate improvements in the efficiency by factors of up to 2.9 at the resonant wavelength. The lowest switching voltage, Vπ , is 4.5 V
