• We studied theoretically and experimentally an InGaAs/InAlAs/InP polarization-insensitive multiple quantum well(MQW) electroabsorption(EA) modulator operating over a very wide wavelength range in 1.55μm wavelength region. One of the simplest possible potential-tailored quantum well, "pre-biased"quantum well(PBQW) is used to achieve wide-wavelength polarization insensitivity. PBQW is basically a rectangular quantum well with a thin barrier inserted near one edge of well. This thin barrier effectively introduces"pre-bias"to a rectangular quantum well and the same amount of Stark shift is achieved for electron-heavy hole and electron-light hole transition energies. By incorporating tensile strain into PBQW, polarization-insensitive modulation is achieved over 60nm wavelength range, from 1510nm to 1570nm. This MQW-EA modulator plays an important role in wavelength division multiplexing(WDM) transmission and switching systems.
