Electrical Control of Lifetime-Limited Quantum Emitters Using 2D Materials.

Area of Science:

• Quantum nanophotonics
• Solid-state quantum emitters
• 2D materials

Background:

• Solid-state quantum emitters are crucial for quantum nanophotonics, serving as single-photon sources (SPS) and optical nanoprobes.
• Integrating emitters with nanophotonic elements offers control but often compromises emitter photostability.

Purpose of the Study:

• To demonstrate a tunable hybrid device integrating quantum emitters and 2D materials.
• To achieve efficient control of optical properties without degrading emitter performance.
• To develop an integrated, ultracompact tunable SPS and a novel nanoprobe for 2D material sensing.

Main Methods:

• Integration of state-of-the-art lifetime-limited single emitters with 2D materials at subwavelength separation.
• Fabrication of nanoscale hybrid device enabling ultrabroadband tuning and fast modulation of emission energy.

Main Results:

• Demonstrated successful integration without degradation of emission properties.
• Achieved ultrabroadband tuning (>400 GHz) and fast modulation (frequency ~100 MHz).
• Developed a tunable single-photon source and a nanoprobe for 2D material sensing.

Conclusions:

• The hybrid device offers efficient control of quantum emitters and 2D materials.
• Enables development of integrated, ultracompact tunable single-photon sources.
• Provides a novel approach for optical sensing of 2D material properties using quantum emitters.
