Abstract

We report observation of enhanced correlation, wavelength shifting, and spectral broadening of the twin beams in a parametric amplification with a gain greater than 30 dB in a 1.7 m microstructure fiber.

Observation of twin-beam-type quantum correlation in optical fiber

Jay E. Sharping, Marco Fiorentino B, Prem Kumar

We report generation of pulsed twin beams of light through optical parametric amplification in a fiber Sagnac loop. By pumping the Sagnac loop with picosecond pulses at a wavelength near the zero-dispersion wavelength of the fiber, we achieve phase-matched nondegenerate four-wave mixing with gain. For a gain of 2.2, the intensity noises of the amplified signal and the generated idler (conjugate) pulses are found to be correlated by 5.0 dB, and the subtracted noise drops below the shot-noise limit by 1.1 dB (2.6 dB when corrected for losses). We have investigated the gain dependence of the quantum-noise reduction as well as of the intensity noises of the amplified signal and idler pulses. As the gain increases, we observe the onset of excess noise on the idler pulses.

Multimode theory of pulsed-twin-beam generation using a high-gain fiber-optical parametric amplifier

We theoretically investigate the quantum-noise properties of a pulse-pumped high-gain-fiber optical parametric amplifiers (FOPAs) by using the Bogoliubov transformation in multiple frequency modes to describe the evolution of the nondegenerate signal and idler twin beams. The results show that the noise figure of the FOPA is generally greater than the 3 dB quantum limit unless the joint spectral function is factorable and the spectrum of the input signal well matches the gain spectrum in the signal band. However, the intensity-difference noise of the twin beams, which weakly depends on the joint spectral function, can be significantly less than the shot-noise limit when the temporal modes of the pump and the input signal are properly matched. Moreover, to closely resemble real experimental conditions, the quantum noise of twin beams generated from a broadband FOPA is numerically studied by taking the various kinds of experimental imperfections into account. Our study is not only useful for developing a compact fiber source of twin beams, but also helpful for understanding the quantum-noise limit of a pulse-pumped FOPA in the fiber communication system.

Polarization-independent wavelength conversion with a gain using two-pump fiber parametric amplification without idler spectral broadening

Takuo Tanemura, Kazuro Kikuchi

A simple scheme for a highly efficient polarization-independent wavelength converter utilizing fiber parametric amplification is demonstrated. We use two orthogonally polarized pumps, which are BPSK-modulated to obtain a broadband parametric gain without idler spectral broadening.
