We demonstrate broadband spectral phase conjugation based on temporal imaging via four-wave mixing and show for the first time compensation of pulse distortions due to second- and third-order dispersion and self-phase modulation.
We model the phase coherence of multi-transverse modes of buried-heterostructure quantum cascade lasers. The experimentally observed transverse mode locking and beam steering are explained by four-wave mixing of longitudinal modes belonging to different transverse modes.
Four-wave mixing in semiconductor quantum wells has long been used to investigate many-particle effects. We introduce the theoretical concepts and illustrate some developments of the field, which D.S. Chemla helped to shape.
Efficient generation of a cascade of four-wave mixing products using a low-dispersion highly nonlinear fiber is demonstrated. The measured optical frequency comb (with a spacing of 100 GHz) spans over more than 350 nm.
A 100-nm comb of optical frequencies spaced by 400 GHz at 790 nm was obtained by second harmonic generation of an optical frequency comb produced by multiple four-wave-mixing in a highly nonlinear optical fiber.
Four-wave mixing between a coherent laser signal and incoherent pump in highly nonlinear fiber are investigated theoretically and experimentally, and the effect of incoherence pump on signal is studied.
A new type of tellurite glass has been synthesized with composition 70%TeO2-25%ZnO-5%ZnS. The glass is of black color, indicating a high absorption in the visible range. However, transmittance measurements show the same glass to be transmitting in the near-IR range, between 2 mum and 6 mum. XPS data reveal the existence of Zn-O-S and a reduction of tellurium oxide with formation of Te-Te bonds in...
We demonstrate four-wave mixing in silicon nitride waveguides with -7.1 dB conversion efficiency between the signal and idler. We observe no evidence of nonlinear losses with pump powers as high as 110 W.
We experimentally demonstrate a compact optical auto-correlation peak discriminator based on four-wave mixing in a highly-nonlinear bismuth-oxide fiber. The discriminator rejects cross-correlation peaks, thus improves the detection of optical CDMA signal and removes the error-floor.
We report the first, to the best of our knowledge, experiment on the separation of the microscopic cascaded contribution to the fifth-order nonlinear susceptibility, which comes from the third-order microscopic hyperpolarizability.
We experimentally demonstrate photon pair production in standard single-mode optical fibers via spontaneous four-wave mixing. The process utilizes birefringent phase matching to control the photon pair joint spectral structure.
We demonstrate efficient modulation of four-wave mixing in a Rb-waveguide system via application of a weak ldquoswitchingrdquo field. We observe 3 dB attenuation of the signal field with only 3600 photons of ldquoswitchingrdquo energy.
It is shown that adiabatic manipulation of a Raman process allows us to produce an optical-frequency-comb from single-frequency lasers. The carrier-envelope-offset frequency of the generated octave-spanning Raman comb is stabilized to an optical-frequency-standard.
We demonstrate Fourier synthesis of RN-like multiple coherent anti-Stokes Raman-scattering signals in a KTaO3 single crystal at room temperature. Isolated pulses with 13-fs duration and 520-690-nm wavelength range are generated without any active chirp compensator.
We analyze the dependence of the polarization of THz radiation generated by four-wave-mixing in laser induced plasma filaments on the input polarizations and compare these results to current models for plasma assisted THz generation.
We demonstrate 160-Gb/s wavelength conversion across 21 nm in the C-band using four-wave mixing in dispersion-engineered silicon photonic waveguides. Measurements show a conversion efficiency of -15.5 dB and a pulse broadening factor of 38%.
We experimentally investigate wavelength conversion in quantum-dot semiconductor optical amplifiers via four-wave mixing. Using four 40-GHz probes we demonstrate greater than 100% conversion over 160 GHz with a large signal-to-noise ratio.
We demonstrate use of all optical mixing in a highly nonlinear fiber to achieve microwave photonic frequency measurement. The system is simple, compact, predictable and stable with potential applications in next generation radar warning receivers.
We present a PCF photon pair source with signal and idler emission in the visible and near-infrared wavelength regions. Our joint spectral coincidence measurements indicate that the generation of spectrally decorrelated photon pairs is possible.
We demonstrate frequency magnification by a factor of 105 using a spectral imaging system with two four-wave mixing based time-lenses. We achieve a 1-GHz frequency resolution.
