中文摘要	to overcome the isotropic directional emission of an ideal circular microdisk, two kinds of cylindrical mesa-like ingaalp single quantum well (sqw) microdisks emitting at a visible red wavelength of 0.66 mu m have been fabricated. an anisotropic luminescence pattern was revealed by the microscopic fluorescence (fl) image. fl intensity, preferentially enhanced with twofold symmetry, appeared at the circumference of the ingaalp sqw microdisks. our results demonstrated that anisotropic radiation can be achieved by geometry shaping of the disks on the top view two-dimensional boundary slightly deformed from circular shape and/or on the side-view cross-section of the circular mesa by wet etching anisotropic undercut.
