At 1550 nm, an input peak intensity of 28 GW/cm2 (before the waveguide) results in 30% power switching in a 2-cm-long waveguide. Numerical studies show that we can make the nonlinear switching more efficient by using the nonlinear anisotropy in a multiple-quantum-well waveguide. © 1993 Optical Society of America.en-USLight polarization; Semiconducting aluminum compounds; Semiconductor materials; Semiconductor quantum wells; Switching systems; Band gaps; Polarization switching; Nonlinear opticsjournal article10.1364/OL.18.0014872-s2.0-0027653356
