“…Because intensity (I ) is proportional to the square of the electric field (i.e., I = E 2 (ω)/2), The Kerr Effect has a quadratic dependence with the electric field [20]. The Kerr effect can be advantageously exploited for optical parametric-amplification frequency conversion [24], optical phase conjugation [25], and pulse compression and regeneration [26].…”

Optical fibers have become ubiquitous tools for the creation, propagation, manipulation, and detection of light. However, while the intensity of light propagating through the fiber can increase or decrease along the length through amplification or attenuation, respectively, the properties of the fiber itself generally do not, thus removing an opportunity to further control the behavior of light and performance of fiber-based devices. Shown here are optical fibers that exhibit significant changes in their longitudinal optical properties, specifically a tailored longitudinal numerical aperture change of about 12% over less than 20 meters of length. This is about 1900 times greater than previously reported. The Brillouin gain coefficient was found to decrease by over 6 dB relative to a standard commercial single mode fiber. Next generation analogs are expected to exhibit more than a 10 dB reduction in SBS gain using larger, yet still reasonably manufacturable gradients over practical lengths.

“…A dispersion compensator, based on bulk diffraction grating and MEMS mirrors 12 , is capable of individually addressing varying amounts of residual dispersion in different WDM channels, but with a relatively small tuning range. A novel device is designed based on selfphase modulation (SPM) effect in a specially designed highly nonlinear positive dispersion fiber (HNL-PDF) [13][14][15] . This fiber-based nonlinear device presents several unique advantages, including potentially broadband and wavelength-continuous operation, the ability to individually address different amounts of residual dispersion in different WDM channels, and the possibility to achieve simultaneous dynamic dispersion compensation and noise compression (2R regeneration).…”

The capacity limit of a thermally controlled fiber Bragg grating-based chromatic dispersion compensator, which was initially designed for 10 Gb/s operation, was investigated in a 40 Gb/s system. A CS-RZ DQPSK polarization division multiplex (PolDM) system was used as a testbed. An equivalent quasi error-free 5.94 Tb/s capacity was demonstrated when dispersion of up to 73.8 km of SSMF was compensated. The dispersion slope compensation was satisfactory for C-band operation. Additionally, it was found that the compensator introduced band-pass filtering behaviour, which reduced the compensator bandwidth as the dispersion setting was increased. It was also found that even after 41.5 km, there was around 2 dB penalty introduced to DQPSK system while 5 dB penalty to DQPDKPolDM, referring to BER of 10 -5 .

Dynamic dispersion compensation based on non-linear self-phase modulation (SPM) in an all-fiber device is demonstrated. The basic design of the compensator is very simple, consisting only of a pre-compensating negative dispersion fiber, an optical amplifier, and a highly non-linear positive dispersion fiber. Multiple channel operation of the compensator is feasible and experimentally demonstrated. An increase of dispersion tolerance of at least a factor of 2 is shown with low penalty of less than 2 dB. Finally, device performance in a 2000 km fiber loop experiment is presented.
