Abstract
Electroabsorptive modulators require large depth of modulation and maximum length of inβout linearity. A systematic approach to optimize the operation of these modulators based on quantumβconfined Stark effect is presented here. The conventional operation of differential modulator, following span linearity maximization by adjusting the incident power of laser beams and modulation depth enhancement by reverse bias voltage adjustment, is presented. The results show the optimum bias voltage as 8 V and read out beam power as 175 nW. Β© 2009 Wiley Periodicals, Inc.
