24 Feb 2008TL;DR: In this paper, a silicon photonics slot waveguide with a record nonlinearity of 104 000 W-1km-1at 1.5?m is reported. And they demonstrate demultiplexing of 130 Gbps signals to 10 Gbps using FWM in a 6 mm-long device.
Abstract: A silicon photonics slot waveguide with a record nonlinearity of 104 000 W-1km-1at 1.5 ?m is reported. We demonstrate demultiplexing of 130 Gbit/s signals to 10 Gbit/s using FWM in a 6 mm-long device.

TL;DR: In this paper, the third-order susceptibilities of new bidisithiafulvenyl-substituted tetrathiafulvalene derivatives were measured using the degenerate four-wave mixing method.
Abstract: We measured the third-order susceptibilities χijkl〈3〉 of new bisdithiafulvenyl-substituted tetrathiafulvalene, using the degenerate four-wave mixing method. From these measurements we deduced the values of the second-order hyperpolarizabilities γ and their molecular and electronic contributions. We compared the third-order optical properties of these new extended tetrathiafulvalene derivatives with the properties of acetylenic and ethylenic analogs of tetrathiafulvalene that we studied previously. All organic molecules studied here revealed large third-order nonlinear optical hyperpolarizability.

TL;DR: A review of the main directions of development, the most promising new techniques, and urgent applications of coherent four-photon methods of investigation of excited and ionized gas media is presented in this article.
Abstract: A review of the main directions of development, the most promising new techniques, and urgent applications of coherent four-photon methods of investigation of excited and ionized gas media is presented. It is demonstrated that the methods of coherent four-wave mixing (FWM) provide important spectrochronographic information on atoms and ions, allow selective studies of separate components of nonstationary gas and plasma systems with a complex composition using polarization-sensitive four-photon spectroscopy and coherent ellipsometry, and permit nonlinear-optical imaging of the spatial distribution of atoms and ions in excited gases and plasmas.

TL;DR: This is the first demonstration of kilohertz-level intensity-difference squeezing using a semiconductor laser as the pump source and would extend the range of possible applications for squeezing due to its low cost, ease of operation, and ease of integration.
Abstract: Using a nondegenerate four-wave mixing process in hot rubidium vapor, we demonstrate a compact diode-laser-pumped system for the generation of intensity-difference squeezing down to 8 kHz with a maximum squeezing of −7 dB. To the best of our knowledge, this is the first demonstration of kilohertz-level intensity-difference squeezing using a semiconductor laser as the pump source. This scheme is of interest for experiments involving atomic ensembles, quantum communications, and precision measurements. The diode-laser-pumped system would extend the range of possible applications for squeezing due to its low cost, ease of operation, and ease of integration.
