Highly Efficient Arbitrary Wavelength Conversion Within Entire C-Band Based on Nondegenerate Fiber Four-Wave Mixing

Quantum frequency translation by four-wave mixing in a fiber: low-conversion regime

“…This process has been used classically to allow FC (frequency conversion) over a wide frequency range [27][28][29]. The advantages of BS are that it is tunable [30], has low-noise transfer [31], and allows for very distant FC (more than 200 nm) [32,33]. BS has also been used to FC single photons [34].…”

Effects of nonlinear phase modulation on Bragg scattering in the low-conversion regime

“…Like TWM, BS converts while adding the minimum excess noise required by the Heisenberg uncertainty principle [26,27]. However, among the many advantages of using FWM for classical FC are that the process is highly tunable [25,28], BS allows for very distant conversion (more than 200 nm was demonstrated in [29,30]) and in contrast to TWM, it also allows conversion of signals placed near each other. Another important property is that because BS is fiber-based, the modes emitted in the process are already mode-matched to the propagation medium.…”

Semiconductor Optical Amplifiers and their Application for All Optical Wavelength Conversion

“…In order to enhance FWM special phase matching and quasi phase matching techniques have been employed with exceptional bandwidth and efficiency demonstrated for devices based on periodically poled LiNbO3 devices (Yamawaku et al, 2003). Similarly, careful tailoring of single mode fiber dispersion, has also allowed for highly efficient FWM in highly non-linear fibers (HNLF) (Tanemura et al, 2004). However in the stride for small foot-print and low power options, a more useful solution is the employment of an SOA as a non-linear medium, as it offers integration potential and may contribute significant signal gain to offset the negative conversion efficiency.…”
