Abstract: The authors report on the fabrication of hybrid planar microresonators based on InGaAs microdisks with an evaporated organic material. Samples of InGaAs grown on InP(100) substrates are obtained by Chemical Beam Epitaxy, and microdisks of InGaAs with different diameters are fabricated by focused ion beam. The hybrid disks are obtained by the subsequent evaporation of 8-hydroxyquinoline aluminium doped with 4-Dicyanomethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran on the InGaAs microdisks. The devices, characterized by micro-and confocal photoluminescence imaging and spectroscopy, exhibit emission around 650 nm, from the organic material for disks with different radius. Finally, simultaneous emission in the visible and at whispering gallery resonant modes in the 1350-1450 nm range are observed due to excitation transfer to InGaAs. These devices open the possibility to combine the flexibility of organics with the high gain of III-V compounds for wavelength down conversion and telecom applications.
