Abstract

Enhanced electrooptic coefficient of GaInAsP three-step quantum wells (3SQW) for high power electrorefraction modulator applications is reported. Measured electrooptic coefficient of the 3SQW is nearly three times higher than the conventional rectangular quantum well (RQW) at lambda=1.55 um. Higher electrooptic effect, combined with a low optical absorption coefficient α<1 cm-1 in the 3SQW increased the modulator figure of merit by nearly 53 times, and decreased the power consumption by nearly one order of magnitude compared with a conventional RQW design.
