Nonlinear Guided Waves and Their Applications

Interference between photon echoes in an Er-doped fiber

Abstract

We report the observation of a new interference phenomenon in photon echo experiments which are performed in an optical fiber. This phenomenon is unique to the guided wave environment and is the result of propagation in an optically thick absorber. The use of optical fibers allows long interaction lengths where the propagation of the excitation pulses as well as the echoes is important.

Coherent Effects in Er-doped Fibers: Photon-Echo with Femtosecond Pulses

Yaron R. Silberberg, Valéria Loureiro da Silva, J.P. Heritage +3 more

Optical fibers have proven to be one of the most important nonlinear media, even though in most cases the nonlinearity exploited is the notoriously weak Kerr effect of the silica-based fiber. By using doped fibers, new, stronger nonlinearities are possible. These stronger effects could allow for new phenomena and applications. Coherent effects, in particular, should be important when pulses shorter or comparable to the dephasing time of the impurity ions propagate in the fiber. Here we report, for the first time, the observation of accumulated photon-echo and free induction decay during the propagation of femtosecond pulses in Er doped fibers at 4.2°K.

Photon echoes in an optical amplifier

Valéria Loureiro da Silva, Yaron R. Silberberg

Accumulated photon-echo experiments in pumped Er-doped fibers are reported. The echoes were observed to decrease and disappear as the fiber was pumped to transparency, and then to increase again as the system was inverted. Coherent saturation between the pulses unbalanced the initially identical excitation pulses. We describe a simple frequency domain model that explains all the observed features.

Photon-Echoes in a Pumped Er-Doped Fiber

Valéria Loureiro da Silva, Yaron R. Silberberg

Recently we reported the first photon echo experiments in Er-doped fibers, and described their application to ultrafast time domain signal processing [1]. Our previous results were obtained with absorbing Er-doped fibers at 4°K, and our signals at 1.53µm were attenuated by the fiber. In this paper we report photon echo experiments with Er-doped amplifiers. We expect the photon echo process in amplifiers to yield strong echoes, perhaps stronger then the input signal. This could be important for signal processing applications. To our knowledge this is the first demonstration of photon echo in any inverted system.

Femtosecond accumulated photon echo in Er-doped fibers

We report the observation of accumulated photon echo in Er-doped fibers. We also demonstrate time reversal and autoconvolution of femtosecond pulses, which suggest that Er-doped fibers are a promising medium for femtosecond time-domain optical signal processing.

Photon-echo in Er-doped fibers: a new approach to femtosecond time-domain optical signal processing

V.L. da Silva, Yaron R. Silberberg, J.P. Heritage +3 more

Recently, interest in photon echo has been revived because of its potential application in time-domain optical memories1. Several demonstrations have been reported in gases and also bulk organic and inorganic materials at cryogenic temperatures2-4. In this paper, we report the observation of accumulated photon echo in Er doped optical fibers and demonstrate that these fibers can be used to store information on the subpicosecond time scale.

Self-induced transparency soliton propagation in an erbium-doped optical fiber waveguide

Masataka Nakazawa, Yasuo N. Kimura, Kazunori Suzuki +2 more

The recent development of the EDFA (erbium-doped fiber amplifier) offers the possibility for uses of the fibers to experiments on coherent pulse propagation such as self-induced transparency (SIT). The guiding of the radiation by the fiber structure eliminates diffraction effects and makes possible the interaction of the radiation with the fiber medium which has resonance effects over long distances. To date, however, experiments on SIT solitons have suffered from diffraction effects that were further complicated by nonlinear interactions. In the present paper, we report for the first time the observation of SIT soliton propagation in an erbium- doped resonant fiber waveguide.
