Abstract
An optical autocorrelator grown on a (211)B GaAs substrate that uses v isible surface-emitted second-harmonic generation is demonstrated. The (211)B orientation needs TE mode excitation only, thus eliminating the problem of the beating between the TE and TM modes that is required f or (100)-grown devices; it also has the advantage of giving higher upc onversion efficiency than (111) growth. Values of waveguide loss and t he difference in the effective refractive index between the TE(0) and TE(1) modes were also obtained from the autocorrelation experiment.
