“…The generated idler on the other hand will shift its frequency twice as much as the frequency deviation of the pump, thus leading to a broadening of the idler spectrum to twice the spectral width of the phase-modulated pump. Yang et al proposed in [4] a dual pump scheme using pumps with a relative phase difference of the electrical PM frequency of as a method to compensate for the idler broadening. Fig.…”

“…The fiber-based OPA is a well-known technique offering discrete or "lumped" gain using only a few hundred meters of fiber [4], [5]. It offers a wide gain bandwidth and may in similarity with the Raman amplifier [6] be tailored to operate at any wavelength [7]- [11].…”

Abstract-An applications-oriented review of optical parametric amplifiers in fiber communications is presented. The emphasis is on parametric amplifiers in general and single pumped parametric amplifiers in particular. While a theoretical framework based on highly efficient four-photon mixing is provided, the focus is on the intriguing applications enabled by the parametric gain, such as all-optical signal sampling, time-demultiplexing, pulse generation, and wavelength conversion. As these amplifiers offer high gain and low noise at arbitrary wavelengths with proper fiber design and pump wavelength allocation, they are also candidate enablers to increase overall wavelength-division-multiplexing system capacities similar to the more well-known Raman amplifiers. Similarities and distinctions between Raman and parametric amplifiers will also be addressed. Since the first fiber-based parametric amplifier experiments providing net continuous-wave gain in the for the optical fiber communication applications interesting 1.5-m region were only conducted about two years ago, there is reason to believe that substantial progress may be made in the future, perhaps involving "holey fibers" to further enhance the nonlinearity and thus the gain. This together with the emergence of practical and inexpensive high-power pump lasers may in many cases prove fiber-based parametric amplifiers to be a desired implementation in optical communication systems.

“…Both high bandwidth of up to 208 nm [1] and also high gain of up to 70 dB [2] have been demonstrated. Furthermore, the FOPA has additional functionalities such as wavelength conversion [3], demultiplexing [4] and signal regeneration [5]. In this work, a single pump FOPA is described where only one strong pump ampli es a weak signal in a highly nonlinear ber (HNLF).…”

“…It is a well known observation [6] that the dithering of the pump signal to suppress Stimulated Brillouin Scattering (SBS) in a FWM experiment produces a broadening of the idler signal; this broadening is generally regarded as an undesirable side effect. We theoretically and experimentally demonstrate that the frequency chirp characteristics of the pump signal are faithfully reproduced in the idler, which implies that the chirp-doubled signal can be used for higher resolution optical imaging.…”

Abstract-We present an analysis and demonstration of the doubling of the chirp rate and total chirp bandwidth of a frequency chirped optical signal by the process of four-wave mixing in a non-linear optical medium. The effects of chromatic dispersion and input power on the maximum achievable output bandwidth are analyzed, and a dispersion compensation technique for phase matching is described. The doubling of an input linear frequency sweep of 100 GHz/1 ms in a highly nonlinear optical fiber is experimentally demonstrated. Further, it is proposed that a cascaded implementation of the four-wave mixing process leads to a geometric increase in the bandwidth of the frequency chirp. With an electronically tuned chirped laser at the input stage, this process can be used to generate extremely wideband swept frequency sources with no moving parts, for applications in high-speed and high-resolution optical imaging and spectroscopy.
