Original scientific paper
The results of the high speed response of GaAs/AlGaAs multiple quantum well (MQW) base
asymmetric Fabry Perot (ASFP) reflection modulator are presented. The measured 3 dB
electrical frequency response bandwidth of the modulator was 600 MHz at an applied
voltage of only 5 V at 854 nm wavelength. The contrast of the modulator was
8.9 dB for a driving voltage of 13 V, at an operating wavelength of 862 nm.
