  • Abstract
    A passive GaAs/Al0.8Ga0.2As green surface-emitting second-harmonic generator grown on a [211]B GaAs substrate is demonstrated. This orientation offers the same up-conversion efficiency as [110] devices without requiring etched waveguide facets. The GaAs and Al0.8Ga0.2As second-harmonic coefficients are determined from the measured up-conversion efficiencies for TE0 and TM0 mode excitation.
