- Abstract: A scalable source of single photons is a key constituent of an efficient
quantum photonic architecture. To realize this, it is beneficial to have an
ensemble of quantum emitters that can be collectively excited with high
efficiency. Semiconductor quantum dots hold great potential in this context,
due to their excellent photophysical properties. Spectral variability of
quantum dots is commonly regarded as a drawback introduced by the fabrication
method. However, this is beneficial to realize a frequency-multiplexed
single-photon platform. Chirped pulse excitation, relying on the so-called
adiabatic rapid passage, is the most efficient scheme to excite a quantum dot
ensemble due to its immunity to individual quantum dot parameters. Yet, the
existing methods of generating chirped laser pulses to excite a quantum emitter
are bulky, lossy, and mechanically unstable, which severely hampers the
prospects of a quantum dot photon source. Here, we present a compact, robust,
and high-efficiency alternative for chirped pulse excitation of solid-state
quantum emitters. Our simple plug-and-play module consists of chirped fiber
Bragg gratings (CFBGs), fabricated via femtosecond inscription, to provide high
values of dispersion in the near-infrared spectral range, where the quantum
dots emit. We characterize and benchmark the performance of our method via
chirped excitation of a GaAs quantum dot, establishing high-fidelity
single-photon generation. Our highly versatile chirping module coupled to a
photon source is a significant milestone toward realizing practical quantum
photonic devices.
