Abstract :
An integrated Mach-Zehnder intensity modulator for laser radiation at the wavelength 780 nm is demonstrated for the first time. The device features a double heterostructure GaAs/AlGaAs electro-optic phase modulator. The estimated insertion loss is less than 2.5 dB and the extinction ratio is 3.3 dB.
