Abstract
We report on design, simulation and fabrication of ultimate and compact 3D close-geometries optical microcavities. These are based on the extension of the so-called 2.5D nanophotonic approach where a quasi 3D control of the photons has been soon demonstrated by our group. A tight control of photons, spectrally and spatially, in a small air region inside a circular regular pattern of high index material-based nanopillars is demonstrated when adjusting the number of pillars, their diameters and the diameter of the pillar-circle. Bottom-up approach based on InP nanowires grown by molecular beam epitaxy and top-down approach based on high aspect ratio anisotropic etching have been developed for fabricating these optical microcavities.
