Novel microcavities are fabricated that consist of GaAs microdisks (-3 l m diameter) sandwiched betwecn AlAs cladding, bounded by a circular grating of deeply etched air trenches.An enutting layer of I d s quantum dots is insend in GaAs.The prating acts as a 4thorder Bragg reflector for the in-plane cavity, so that some 2nd-order diffraclion towards air can occur.This allows to Microdirks modes usually requlre lugh azimuthal number 1 to be confined through toral internal reflection, while drum-like modes with low-azimuthal number I only see the poorer norms1 reflection at the semiconductor-air interface (30%).In our cavity, the circular Bragg mirror ic
