A phase-sensitive amplifier followed by a phase-insensitive one can have a noise figure well below 3dB. This can be used for reducing the detrimental nonlinear effects occurring in fiber optical parametric amplifiers for optical communication.

We report reduction of cross gain modulation to less than 1 dB by using gain clamping in a fiber optical parametric amplifier. Power penalties were improved from 2.5 dB to 0.5 dB.

Degenerate four-wave mixing (DFWM) in optical fibres can be used to obtain gain and to generate squeezed states, by utilizing a balanced Mach-Zehnder fibre interferometer (MZFI) with two non-linear arms, which behaves as a degenerate parametric ampli

The full vector modal solutions and losses of a biconcave infrared (IR) waveguide are determined using a boundary layer analysis of Maxwell’s equations. The conditions on the surface of the guide are given by an effective impedance condition arisin

Recently we have shown theoretically that two-pump fiber optical parametric amplifiers (OPA’s) can exhibit highly uniform broadband gain spectra [1]: for example one can obtain 20 dB of gain over a 45 nm bandwidth, with uniformity of 0.2 dB. These

We have recently shown theoretically that a two-pump fiber optical parametric amplifier (OPA), operated near the fiber zero-dispersion wavelength, λ0, can exhibit very uniform gain over a wide wavelength range [1]. For example, a standard dispersion

In order to be useful in a wide range of communication applications, fiber optical parametric amplifiers (OPA’s) and wavelength converters should operate on a cw basis. Furthermore, conversion efficiency Gi should be greater than or equal to one, i

The third-order nonlinearity in optical fibers is the cause of the related phenomena of self-phase modulation (SPM), four-wave mixing (FWM), and cross-phase modulation (XPM). The FWM generation efficiency in a single fiber segment depends on the prop

A nonlinear Mach-Zehnder fiber-optic interferometer as shown in Fig. 1 can be used for light squeezing1 and amplification.2 The mechanism can be viewed either as the Kerr effect,1 or degenerate four-wave mixing (DFWM).2 Using the classical DFWM appro
