Abstract

Efficient electroabsorption in an InGaAsP/InGaAsP MQW optical waveguide modulator structure is reported. A 17 dB extinction ratio is obtained by applying a 3.5 V drive voltage to a 78 μm long waveguide operating at 1.54 μm under TE-polarisation mode. The on-state attenuation is only 2 dB.
