Low optical insertion-loss and vacuum-pressure all-fiber acetylene cell based on hollow-core photonic crystal fiber

Abstract

We report a novel and easy-to-implement hollow-core photonic crystal fiber cell fabrication technique based on helium diffusion through silica. The formed gas cells combine low optical insertion loss (1.8 dB) and vacuum acetylene pressure (microbar regime). The estimates of the final gas pressure, using both Voigt interpolation and electromagnetically induced transparency, show a good match with the initial fitting pressure.

Integration of hollow-core-photonic crystal fiber in all-fiber devices

Fetah Benabid

The good optical transmission of hollow-core photonic crystal fiber and their relative low insertion loss in conventional fiber network gave rise to a new type of all-fiber gas-phase devices. These range from Raman converters as laser sources, compact frequency standard devices for laser frequency control to electromagnetically-induced transparency and saturable absorption for quantum optical devices. Here I report on the performance of these devices and their prospects.

Transient quantum coherent effects in the acetylene-filled hollow-core photonic crystal fiber

Serguei I. Stepanov, Nayeli Casillas, Manuel Ocegueda +1 more

Low-pressure acetylene in the hollow-core photonic crystal structure fibers is an excellent medium for the room-temperature investigation of the coherent quantum effects in communication wavelength region. Pulsed excitation enables observation of new coherent phenomena like optical nutation or photon echo and evaluation of important temporal characteristics of the light-molecule interactions. We also report original experimental results on the pulsed excitation of the electromagnetically induced transparency in co- and counter-propagation configurations.

Experimental setup for electromagnetically induced transparency observation in hollow-core fibers

Bruno D. Tibúrcio, Gil M. Fernandes, Jorge H. Monteiro +5 more

We developed a system to investigate resonant nonlinear optical interactions in acetylene molecules, confined in a hollow-core photonic crystal fiber (HC-PCF), using light injection through a low-loss splice from one end of the fiber, allowing us to work at low power. Electromagnetically induced transparency (EIT) was observed in the 1500 nm telecommunications window.

Photonic microcells for quantum optics applications

P. S. Light

This thesis presents the development of photonic microcells for use as the host for coherent optics phenomena and related applications. A photonic microcell consists of a length of hollow-core photonic crystal fibre (HC-PCF) with a gas-filled core that is spliced to conventional optical fibre at either end to seal the gas within the fibre. Towards the goal of demonstrating and assessing the coherence properties of quantum optical effects in photonic microcells, the fabrication of two types of HC-PCF is presented. The established photonic bandgap HC-PCF offers extremely low transmission loss of ~10 dB/km over kilometre distances. However, the fibre has a limited transmission bandwidth of ~50 THz and exhibits modal coupling unfavourable for many applications. Work is presented on the tailoring of this fibre by control and shaping of the core-surround in order to improve its modal properties. A second type of HC-PCF is based on a large-pitch lattice, whose guidance relies on a new mechanism. This fibre exhibits a much improved bandwidth (>1000 THz) and has a relatively higher but still practical loss of ~1 dB/m. The development of photonic microcells at microbar pressure level and with low optical insertion loss is shown, an important step in the improvement of the technology for coherent optics applications which will take advantage of the extreme gas-laser interaction efficiency achieved in HC-PCF. Finally, quantum optical effects are demonstrated in HC-PCF and photonic microcells loaded with both the molecular gas acetylene and atomic vapour rubidium. The observation of electromagnetically induced transparency (EIT) in acetylene-filled HC-PCF represents the first such observation in a molecular gas, while the use of a photonic microcell allows a comparison of many experimental configurations to explore the coherence properties of coherent optical systems in the core of a HC-PCF. Furthermore, EIT is observed unambiguously in a rubidium loaded HC-PCF for the first time, and the anti-relaxation effects of a polymer coating demonstrated in this configuration.

Large-core acetylene-filled photonic microcells made by tapering a hollow-core photonic crystal fiber

Natalie V. Wheeler, Michael D. W. Grogan, P. S. Light +3 more

We report on kagomé-lattice photonic microcells with low losses, large outer diameters, and large cores. The large (40-70microm) cores are accommodated by tapering the fibers and splicing the reduced ends to a single-mode fiber. We demonstrate the repeatability of this process and obtain splice losses of 0.6dB by optimizing the taper transition length. Narrow electromagnetically induced transparencies and saturable absorption are demonstrated in an acetylene-filled photonic microcell.

Photon Echo in acetylene-filled hollow-core photonic crystal fibers

Manuel Ocegueda, Eliseo Hernández, Serguei I. Stepanov +2 more

In this work we report on the observation of photon echo inside acetylene-filled hollow-core photonic crystal fibers. The experiments were performed using a sequence of two short (~2ns) optical pulses tuned to the P9 (1530.37 nm) acetylene absorption line. The photon echo effect was observed on the basis of high optical powers (~4 W) and in the acetylene’s low pressure regime <0.5 Torr. The main results prove the formation of photon echo by showing that the obtained echo signals are consistent with the expected behavior, in intensity and optical delay, under variations of the input pulse separation.
