Abstract

The recently developed method of optical homodyne tomography (OHT) allows one to obtain the photon statistics of a single mode with single-photon resolution. Recently, we used OHT to prove the Bose Einstein distribution (BED) character of parametric fluorescence. In general, in an OHT setup, a weak signal beam is mixed on a 50/50 beamsplitter with a strong local oscillator beam of the same polarization and spatio-temporal mode. In this paper, we apply OHT to show, we believe for the first time, that ASE noise of a single mode in an EDFA is Bose-Einstein distributed.

Measurement of the photon statistics and the noise figure of a fiber-optic parametric amplifier

Paul L. Voss, Renyong Tang, Prem Kumar

We report measurement of the noise statistics of spontaneous parametric fluorescence in a fiber parametric amplifier with single-mode, single-photon resolution. We employ optical homodyne tomography for this purpose, which also provides a self-calibrating measurement of the noise figure of the amplifier. The measured photon statistics agree with quantum-mechanical predictions, and the amplifier's noise figure is found to be almost quantum limited.

Photon statistics of single-mode zeros and ones from an erbium-doped fiber amplifier measured by means of homodyne tomography

Paul L. Voss, Michael Vasilyev, Dmitry Levandovsky +2 more

We report measurement of the photon-number distributions of zeros and ones that emerge from an erbium-doped fiber amplifier (EDFA) in an on-off modulated communication system. Single-mode single-photon resolution was achieved by employing the method of optical homodyne tomography. The measured distributions agree with the quantum predictions of a Bose-Einstein distribution for the zeros and a Laguerre (noncentral negative binomial) distribution for the ones over a dynamic range up to 40 dB. The resulting noise figure of the amplifier compares well to that measured by an optical spectrum analyzer.

Self-homodyne Tomography Measurement Of The Photon Statistics Of Parametric Fluorescence

Photon distributions for parametric fluorescence are measured using a novel self-homodyning technique. They exhibit thermal-like character as predicted by the theory. Self-homodyning automatically matches the signal mode with the local oscillator mode.

Photon statistics of a single mode of spontaneous Raman scattering in a distributed Raman amplifier

Paul L. Voss, Yikai Su, Prem Kumar

Experimental measurement of spontaneous noise statistics from a distributed Raman amplifier has been achieved with single-mode and single-photon resolution. The results agree with quantum theoretical predictions of a Bose-Einstein probability distribution. Distributed Raman amplification is becoming increasingly important in today's optical communication systems. It improves the optical signal-to-noise ratio by providing optical gain inside the transmission fiber.

Theoretical Analysis of Noise in Erbium Doped Fiber Amplifier

Alexander William Setiawan Putra, Minoru Yamada, Hiroyuki Tsuda +1 more

Characteristics of noise in erbium doped fiber amplifier (EDFA) are theoretically analyzed and experimentally verified. Four discreet energy models are used for erbium ion transition. Spatially varying photon number for traveling optical field was defined in a spatially divided segment with finite length, whose length is decided by property of the spontaneous emission. Quantitative evaluation of the Langevin noise sources becomes possible by this model. The amplified spontaneous emission was included in terms of discrete longitudinal mode, which is defined for whole length of the EDFA. It was found that the relative intensity noise (RIN) in the EDFA hardly changes with noise frequency in the region higher than several kHz. The phase noise in EDFA also hardly changes with the noise frequency. The frequency noise of the signal light in the EDFA increases proportional to squared value of the noise frequency. The amount of RIN and the phase noise decrease in higher input optical power. Good correspondence between theoretical and experimental results was obtained.
