Single photon nonlinear optics in photonic crystals
We coherently probe a quantum dot that is strongly coupled to a photonic crystal nano-cavity by scattering of a resonant laser beam. The coupled system’s response is highly nonlinear as the quantum dot saturates with nearly one photon per cavity lifetime. This system enables large amplitude and phase shifts of a signal beam via a control beam, both at single photon levels. We demonstrate photon...
متن کاملQuantum 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 کاملReducing noise in single-photon-level frequency conversion.
We demonstrate low-noise and efficient frequency conversion by sum-frequency mixing in a periodically poled LiNbO(3) (PPLN) waveguide. Using a 1556 nm pump, 1302 nm photons are efficiently converted to 709 nm photons. We obtain 70% conversion efficiency in the PPLN waveguide and >50% external conversion efficiency with 600 noise counts per second at peak conversion with continuous-wave pumping....
متن کاملTunable single-photon frequency conversion in a Sagnac interferometer.
Quantum information carriers like photons might be manipulated, stored and transmitted in different quantum systems. It is important to integrate those systems efficiently. The capability of converting photons from one wavelength to another wavelength is a key requirement for combining the photons in telecommunications band for quantum transmission and the photons in near-visible band for quant...
متن کاملSingle Photon Detection Using Frequency Up-Conversion with Pulse Pumping
In any quantum communication system, such as a quantum key distribution (QKD) system, data rates are mainly limited by the system clock rate and the various link losses. While the transmission clock rate is limited by the temporal resolution of the single-photon detectors, losses in a fiber-based quantum communication system can be minimized by operating in the near infrared range (NIR), at 131...
