A new optical modulator has been fabricated which uses the recently discovered electroabsorption effect in multiple quantum wells (MQWs). Optical pulses 131 ps long were generated when the device was driven with 122-ps electrical pulses. The input-output characteristics of the device show that it has low insertion loss with reasonable modulation depth and drive voltage
