Solid-state quantum emitters are a mainstay of quantum nanophotonics as integrated single-photon sources (SPS) and optical nanoprobes. Integrating such emitters with active nanophotonic elements is desirable in order to attain efficient control of their optical properties, but it typically degrades the photostability of the emitter itself. Here, we demonstrate a tunable hybrid device that integrates state of the art lifetime-limited single emitters (line width ∼40 MHz) and 2D materials at subwavelength separation without degradation of the emission properties. Our device’s nanoscale dimensions enable ultrabroadband tuning (tuning range >400 GHz) and fast modulation (frequency ∼100 MHz) of the emission energy, which renders it an integrated, ultracompact tunable SPS. Conversely, this offers a novel approach to optical sensing of 2D material properties using a single emitter as a nanoprobe

The ORQUID board meeting will held at ICFO (Barcelona, Spain) next 17th-18th June, 2019. On day 2, invited speakers will join to present latest research and discuss possible collaborations. 

ORQUID researchers in the Centre for Cold Matter at Imperial College London have recently published work that models and measures the excitation efficiency of DBT molecules in the presence of a tunable laser source, finding that it is highly dependent on the thermally-induced dephasing of the molecule. The article can be found here:
