Abstract
Summary form only given. We report the fabrication of both GaAs-AlAs micropillars and GaAs microdisks displaying an improved optical quality. By optimising the reactive ion etching of micropillars, Q´s as high as 2000 for 1 /spl mu/m diameter pillars could be obtained. Microdisks have been fabricated through a novel process based on a two-step wet etching.
