“…The first experimental realization of a frequency-nondegenerate PSA-amplified transmission link was using single-channel 2.5 Gbit/s non-return-to-zero (NRZ) data transmitted over a 60 km dispersion compensated link [9]. The frequency-and phase-locking of the waves was accomplished using an optical double-sideband modulation scheme [10,11], with the bandwidth limited to the bandwidth of the optical modulators used to generate the sidebands. Following demonstrations have used an all-optical scheme which is based on four-wave mixing (FWM) where the frequency-and phase-locking is achieved through parametric idler creation.…”

Abstract:An injection locking-based pump recovery system for phase-sensitive amplified links, capable of handling 40 dB effective span loss, is demonstrated. Measurements with 10 GBd DQPSK signals show penalty-free recovery of a pump wave, phase modulated with two sinusoidal RF-tones at 0.1 GHz and 0.3 GHz, with 64 dB amplification. The operating power limit for the pump recovery system is experimentally investigated and is governed by the noise transfer and phase modulation transfer characteristics of the injection-locked laser. The corresponding link penalties are explained and quantified. This system enables, for the first time, WDM compatible phase-sensitive amplified links over significant lengths.

“…Fiber-optic parametric amplifiers (FOPA) in a phase sensitive amplification (PSA) configuration are capable of providing noiseless (ideally 0 dB noise figure) optical amplification, while other phase insensitive amplifiers like Erbium Doped Fiber Amplifiers (EDFA) are always limited by a noise figure of at least 3 dB [1][2][3][4]. This attribute of noiseless amplification of PSAs have attracted recent attention in terms of their potential applications in a variety of domains such as microwave photonics, all optical signal processing, longhaul optical communication, free-space satellite communication, quantum technologies, etc.…”

Fiber optic parametric and phase sensitive amplifiers (PSA) are interesting for modern day communication technologies due to their low noise and high gain amplification properties with a potential for all optical signal processing and wide band operation. PSAs are typically employed in either a single pump or dual pump configuration. In this article we explore the utilities of both configurations, however considering a fiber with a longitudinally varying dispersion profile. For the single pump case, PSA operation at large pump-signal detunings, that arise due to the longitudinal dispersion variation, were studied numerically, and recipes of using the system as a wide band wavelength selective filter were laid out. For the dual-pump case, emphasis was laid on achieving a larger signal gain, by reducing stimulated Brillouin scattering (SBS) that prevents large pump power transport through the nonlinear fiber. First, the effects of dispersion variation on the gain of a dual pump PSA were studied analytically and numerically in order to optimize the dispersion variation profile, neglecting SBS processes. Then we independently studied the SBS dynamics of the system numerically. A sinusoidally dispersion oscillating fiber (DOF) was found to be an optimal candidate with respect to its PSA and SBS performances. To establish this claim, we also experimentally compared the performance of an available DOF over a standard highly nonlinear fiber (HNLF) that has a constant dispersion profile and established its utility for designing a high gain PSA system, thanks to the SBS mitigation due to the longitudinal dispersion variation of the fiber.
