摘要
We demonstrate the fabrication and operation of an AlGaAs surface-emitting semiconductor laser, grown by molecular-beam epitaxy, that incorporates a circularly symmetric grating of period LAMBDA = 0.25-mu-m fabricated using electron-beam lithography. Azimuthal variations in the grating linewidth have a significant impact on the spatial modes of the laser.
