Abstract

Dual-pump fiber optical parametric amplifiers offer wide, flat gain spectra across arbitrary wavelengths, often outperforming the use of single-pump designs. However, gain flatness depends on the pump frequencies’ center of gravity relative to the nonlinear fiber’s zero-dispersion wavelength. This study experimentally investigated the gain, gain flatness, and noise figure of degenerate dual-pump fiber-optic phase-sensitive amplification at various separations between these points. We demonstrated 38 dB gain with 1.5 dB gain flatness variation over a 30 nm bandwidth as well as a noise figure below the conventional 3 dB quantum limit for a degenerate signal.

双泵相敏放大器增益谱的泵频分配及色散效应

双泵浦光纤参量放大器可在任意波长范围内提供宽而平坦的增益光谱，通常优于单泵浦设计。然而，增益平坦度取决于泵浦频率相对于非线性光纤的零色散波长的重心。实验研究了简并双泵浦光纤相敏放大器在各点间距处的增益、增益平坦度和噪声系数。我们展示了在30 nm带宽上38db增益和1.5 dB增益平坦度变化，以及低于简并信号的常规3db量子限制的噪声系数。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
