摘要：

We demonstrate the first polarization-independent quantum well waveguide switch. By altering the composition and hence the degree of built-in strain, we engineer the bandgap of In1-xGaxAs/InP quantum wells to produce equal field-induced refractive-index change in TE and TM polarizations. At the same time, the enhanced electrooptic effects characteristic of unstrained quantum wells are maintained, such that the voltage-length product for switching is only 3 V-mm.
