Waveguide Coupled Resonance Fluorescence from On-Chip Quantum Emitter
No full textResonantly driven quantum emitters
offer a very promising route to obtain highly coherent sources of
single photons required for applications in quantum information processing
(QIP). Realizing this for on-chip scalable devices would be important
for scientific advances and practical applications in the field of
integrated quantum optics. Here we report on-chip quantum dot (QD)
resonance fluorescence (RF) efficiently coupled into a single-mode
waveguide, a key component of a photonic integrated circuit, with
a negligible resonant laser background and show that the QD coherence
is enhanced by more than a factor of 4 compared to off-resonant excitation.
Single-photon behavior is confirmed under resonant excitation, and
fast fluctuating charge dynamics are revealed in autocorrelation g<sup>(2)</sup> measurements. The potential for triggered operation is
verified in pulsed RF. These results pave the way to a novel class
of integrated quantum-optical devices for on-chip quantum information
processing with embedded resonantly driven quantum emitters
