“…These include optical switching [50][51][52][53][54][55], phase conjugation [56], wavelength demultiplexing [57][58][59], mode-locking [60][61][62][63][64], pulse compression and pedestal suppression [65][66][67][68][69]. Earlier studies [70][71][72][73][74] have addressed the use of NOLMs to reshape and stabilize soliton pulses.…”

“…Breaking of the loop power symmetry can be done with an asymmetric coupler [49], or alternaltively with a gain or loss element spliced asymmetrically within the loop [77], or alternatively by making the dispersion of the fiber asymmetric [66]. A variation of the NOLM design uses polarization asymmetry between the counterpropagating beams to achieve switching through nonlinear polarization rotation [54]. The NOLM typically exhibits a sinusoidal nonlinear transmission characteristic.…”

All-optical data processing is expected to play a major role in future optical communications. The fiber nonlinear optical loop mirror (NOLM) is a valuable tool in optical signal processing applications. This paper presents an overview of our recent advances in developing NOLM-based all-optical processing techniques for application in fiber-optic communications. The use of in-line NOLMs as a general technique for all-optical passive 2R (reamplification, reshaping) regeneration of return-to-zero (RZ) on-off keyed signals in both high-speed, ultralong-distance transmission systems and terrestrial photonic networks is reviewed. In this context, a theoretical model enabling the description of the stable propagation of carrier pulses with periodic all-optical self-regeneration in fiber systems with in-line deployment of nonlinear optical devices is presented. A novel, simple pulse processing scheme using nonlinear broadening in normal dispersion fiber and loop mirror intensity filtering is described, and its employment is demonstrated as an optical decision element at a RZ receiver as well as an in-line device to realize a transmission technique of periodic all-optical RZ-non-return-to-zero-like format conversion. The important issue of phase-preserving regeneration of phase-encoded signals is also addressed by presenting a new design of NOLM based on distributed Raman amplification in the loop fiber.

In this work we present an optical amplifier elaborated from Erbium-doped fiber (EDF) in reflective configuration. We can obtain bigger amplification with reflective configuration, because the signal is amplified twice in the same EDF. The signal reflection was carried out with a Fiber Bragg Grating (FBG). We use a DFB laser to equalization of 1549.1 nm wavelength. The amplifier was used successfully to investigate the operation of a nonlinear process in optical fibers.
