An optical modulator based on a single strongly coupled quantum dot--cavity system in a p-i-n junction.

چکیده
We demonstrate an optical modulator based on a single quantum dot strongly coupled to a photonic crystal cavity. A vertical p-i-n junction is used to tune the quantum dot and thereby modulate the cavity transmission, with a measured instrument-limited response time of 13 ns. A modulator based on a single quantum dot promises operation at high bandwidth and low power.

Quantum Dots in Photonic Crystals : From Single photon sources to single photon nonlinear optics
A quautmn dot strongly coupled to a photonic crystal resonator is used to investigate cavity quantum electrodynamics phenomena in solid state physics. Nonlinear optical phenomena snch as photon blockade and photon induced tunneling are observed in this system. The nonliJHmrity of this system is sensitive to intra-crwity photon munbers dos<c to unity, aud it has been used to demonstrate conditio...
متن کاملUltrafast photon-photon interaction in a strongly coupled quantum dot-cavity system.
We study dynamics of the interaction between two weak light beams mediated by a strongly coupled quantum dot-photonic crystal cavity system. First, we perform all-optical switching of a weak continuous-wave signal with a pulsed control beam, and then perform switching between two weak pulsed beams (40 ps pulses). Our results show that the quantum dot-nanocavity system enables fast, controllable...
متن کاملOptical manipulation of quantum dot excitons strongly coupled to photonic crystal cavities
In this paper, we review some recent cavity quantum electrodynamic (CQED) experiments with single quantum dot exciton coupled to photonic crystal cavities, performed in our group. We show how the coupled quantumdot/cavity system can be used to modulate light with at a very fundamental level with very low power and discuss some applications of these low power modulators.

Despite tremendous advances in the fundamentals and applications of cavity quantum electrodynamics (CQED), investigations in this field have primarily been limited to optical cavities composed of purely dielectric materials. Here, we demonstrate a hybrid metaldielectric nanocavity design and realize it in the InAs/GaAs quantum photonics platform utilizing angled rotational metal evaporation. Ke...
متن کاملDetuning effect in quantum dynamics of a strongly coupled single quantum dot--cavity system
The quantum dynamics of a strongly coupled single quantum dot–cavity system with non-zero detuning in a phonon bath is investigated theoretically in terms of a perturbation treatment based on a unitary transformation and an operator displacement. The decoherence due to phonons as a function of the detuning between the cavity mode and exciton is obtained analytically. It is shown that the detuni...
