“…However, this noticeable drawback can be quite easily overcome by an additional stage based on a saturable absorber [1,18,19], which have now become suitable for high speed signals up to 160 GHz [27]. We have also shown that this approach presents several beneficial features, such as improved yield or the absence of additional timing jitter in the process.…”

-In this work, we report scaling rules for the design of an all-fibered soliton-based power limiter for reamplification and reshaping (2R) regeneration process. In particular, we propose general guidelines to fix the optimum fiber length and initial power of the regenerator. We quantitatively point out the optical power limiting effect of the device enabling a significant reduction of the amplitude jitter of a degraded signal. Influence of the initial level of amplitude jitter is discussed and the results are compared with a self-phase modulation-based configuration working in the normal dispersion regime. Realistic numerical simulations in the context of 160 Gbit/s signals confirm that an efficient improvement of the signal quality can be achieved by means of such a device.

“…To confirm the effect of our proposed all-optical limiter, we simulated accurate wavelength conversion based on soliton self-frequency shift (SSFS) [13] in Figure 1 as a representative example of stabilized generation of optical nonlinear effect. This phenomenon shows very high sensitivity to small intensity fluctuation.…”

“…Since, however, they are very sensitive to signal intensity fluctuations, optical intensity stabilization comes to be serious issue for the use of nonlinear effects. [9][10][11][12][13][14][15] There are many reports for optical limiting to solve this issue. Among these techniques, the SPM based ones [9], [10], [13], [14], [16] are promising approaches because of its simple composition, stability, and fast operation over 100 Gb/s.…”

We report high-stable wavelength conversion assisted by our proposed optical limiter with preventing influences of 10 GHz intensity fluctuation in simulation. The proposed optical limiter with pre-shaping of input fluctuated pulses enables to achieve high-stable wavelength conversion and a series of processes have no influence on the temporal waveform of converted pulses as well as the converted wavelength.

“…We have also proposed and demonstrated an ultra-fast all-optical intensity limiting function based on intensity-dependent spectral pattern change by self-phase modulation (SPM) and optical pattern recognition technique [8], [9]. Among these techniques, the SPM based ones [1], [2], [5], [8], [9] are promising approaches because of its simple composition, stability, and fast operation over 100 Gb/s. Such techniques have already well-studied and achieved excellent limiting function.…”

Attention will be paid to cooperative use of linear and nonlinear effects in optical signal processing. This talk reports opportunities and significances of understanding of physical phenomena in order to make further advances in cooperative use of linear and nonlinear effects. In this paper, we focus on optical limiting function using self-phase modulation phenomenon and examine carefully its behaviour assisted by time-resolved spectroscopic technology. Based on the results examined, we successfully achieved high-stable optical limiting function. This optical limiting function achieved wavelength conversion based on self-frequency shift phenomena with preventing influences of input intensity fluctuation.
