Abstract
Section titled āAbstractāAbstract We present and investigate a highly directional diamond based optical nanostructure embedded with an elliptical solid immersion lens (e-SIL). An in depth analysis of the far field evolution is elucidated with respect to geometrical modification. This design is capable of producing a maximum directivity of ā¼11 dB at its optimized position. Geometrical tolerance and directional behavior has been studied within a wide range of dipole variation. The incident light source noise is neutralized with the manipulation of e-SIL geometry by considering an experimental simulation environment. Enhancement in directivity near NV center zero phonon line (ZPL) region with reduced excitation light source noise can improve the overall efficiency of the NV single photon emitter and can be useful for multiple photonic applications.
