“…Slicing of the spectrum broadened by SPM is exploited in ( Nishitani et al, 2008;Oda & Maruta, 2005). In (Konishi et al, 2002) the soliton self-frequency shift followed by optical filtering is used. Nevertheless all these techniques, which exploit optical fiber, require high input power and are not suitable for integration.…”

Soliton self-frequency shift (SSFS), a consequence of Raman self-pumping that continuously redshifts a soliton pulse, has been widely studied recently for applications to fiber-based sources and signal processing. In this paper, the fundamentals of SSFS are reviewed. Various fiber platforms for SSFS (single-mode fiber, microstructured fiber, and higher order mode fiber) are presented and experimental SSFS demonstrations in these fibers are discussed. Observation of Cerenkov radiation in fibers exhibiting SSFS is also presented. A number of interesting applications of SSFS, such as wavelength-agile lasers, analog-to-digital conversion, and slow light, are briefly discussed.

“…However, it is difficult to realize a limiter with sharp threshold characteristics. Further, a method has been proposed that uses the self frequency shift of the soliton [7,8]. In this method, it is necessary to prepare optical pulses with a pulse width of several femtoseconds.…”

SUMMARYRecently, research on optical analog-to-digital (A-D) conversion not restricted by the operating speed of electronic devices has been carried out extensively. However, the operation in the optical domain is limited up to sampling. Operations subsequent to quantization are carried out by using electronic devices. The authors proposed a method to realize both sampling and quantization in the A-D conversion simultaneously in the optical domain. In this method, four-wave mixing in the fiber is used for optical sampling and the soliton effects in a fiber are used for optical quantization. In this paper, the principle of the proposed method is described first. Numerical simulation demonstrates its effectiveness. Further, a proof-of-concept experiment is carried out, confirming its realizability.
