This letter explores the design, fabrication and characterization of multimode photonic crystal cavities to support the emission of quantum dots via the Purcell effect. The results showed the existence of three optical resonant modes with high quality factors (~103) as well as achievement of different field distributions to match the positions of quantum dots. Despite that the experimental values of Purcell factor were lower than 5 – compared to theoretical values reaching 100 – the proposed design was successful in light trapping and producing strong resonance. This work shows the possibility to use these multimode cavities to support the control of emission and applications of integrated photonic quantum circuits.
