Abstract

The application of quantum confined Stark effect to realize optical modulators in multiple quantum well (MQW) structures, having p-i-n configuration to apply an external electric field, has been extensively studied by a number of investigators [1-3]. Optical modulation in MQW structures using quantum well charge-coupled devices (QWCCDs) was demonstrated by Goodhue et al [4]. In these devices, the charge packets are transported in the channel by manipulating the gate potentials of the 3-phase CCD array. Jain and Bhattacharjee [5] reported novel modulators using surface acoustic wave induced Stark Effect in the MQW structures without p-i-n device format and associated biasing electrodes.
