TL;DR: In this paper, the phase and amplitude characteristics of nearly degenerate four-wave mixing in a semiconductor laser are studied, and the experimental data can be quantitatively understood with a theoretical analysis in terms of the phase-and amplitude-modulations caused by mixing between the optical fields in the injected laser.

TL;DR: In this paper, a coupled mode formalism is proposed to solve the nonlinear differential equations in the mean field approximation for nearly degenerate four-wave mixing in distributed feedback semiconductor lasers above threshold in investigated theoretically and experimentally.
Abstract: Nearly degenerate four-wave mixing in distributed feedback semiconductor lasers above threshold in investigated theoretically and experimentally. The experimental results reveal an almost symmetric amplification of probe and conjugate fields versus frequency with respect to zero pump-probe detuning, in contrast with observations in traveling wave amplifiers. The result of the theory, based on the coupled mode formalism, is a set of nonlinear differential equations which are solved in the mean field approximation. The theory is shown to match well with the experimental results when the effect of the nonlinear gain compression is taken into account. >

TL;DR: This work reports the first experimental observation of four-wave mixing (FWM) in single-walled carbon nanotubes (SWCNTs) deposited on a Dshaped fiber using a 5-centimeter-long CNT-deposited D-shaped fiber.
Abstract: We report the first experimental observation of four-wave mixing (FWM) in single-walled carbon nanotubes (SWCNTs) deposited on a D-shaped fiber. FWM-based tunable wavelength conversion of a 10 Gb/s non-return-to-zero signal is demonstrated using a 5-centimeter-long CNT-deposited D-shaped fiber. A power penalty of 4 dB power is obtained in the 10 Gb/s bit-error-rate measurements.

TL;DR: In this paper, the authors demonstrate quantum interference of photons on a silicon chip produced from a single ring resonator photon source, which is seamlessly integrated with a Mach-Zehnder interferometer, which path entangles degenerate bi-photons produced via spontaneous four wave mixing in the Silicon ring resonators.
Abstract: Here we demonstrate quantum interference of photons on a Silicon chip produced from a single ring resonator photon source. The source is seamlessly integrated with a Mach-Zehnder interferometer, which path entangles degenerate bi-photons produced via spontaneous four wave mixing in the Silicon ring resonator. The resulting bi-photon N00N state is controlled by varying the relative phase of the integrated Mach-Zehnder interferometer, resulting in high two-photon interference visibilities of V~96%. Furthermore, we show that the interference can be produced using pump wavelengths tuned to all of the ring resonances accessible with our tunable lasers (C+L band). This work is a key demonstration towards the simplified integration of multiple photon sources and quantum circuits together on a monolithic chip, in turn, enabling quantum information chips with much greater complexity and functionality.
