Abstract :
Measurements are presented of hexagonal cavities confined by 2D photonic bandgap boundaries etched in an AlGaAs laser-like waveguide heterostructure. The nominal cavity volumes vary between 0.6 and 1.9 μm3. The photoluminescence of quantum dots embedded in the heterostructure directly probes the cavity horizontal modes and resonances and quality factors of Q≃1000 are observed
