“…Sect. 5 is devoted to review the technologies of a pulse compression fiber so-called comb-like profiled fiber (CPF) [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] that consists of alternate concatenations of HNLF and SMF. The features, the design guideline, and experimental results of optical pulse compression using CPFs are summarized, and we show that CPF is the most suitable for realizing a truly practical and flexible optical pulse source based on fiber-based pulse compressor.…”

“…In some experiments [20,[22][23][24]26], optical beat signals were used as the seed pulses for realizing a pulse source with a large repetition rate, f rep . Although the largest f rep of the compressed pulse train ever demonstrated by using a CPF is f rep = 1 THz [24], much larger f rep would be feasible due to the ultrafast response of fiber nonlinearity.…”

We review optical pulse compression techniques based on optical fibers. After discussing the fundamental issues on pulse compression, we summarize and categorize various kinds of techniques for pulse compression. We then focus on the use of highly nonlinear fiber (HNLF) in a pulse compressor to improve the performance. Introducing a figure of merit, we discuss which kind of HNLF of those recently reported is the most suitable for applications to pulse compression. As a HNLFbased optical pulse compressor, we review the technologies of the comb-like profiled fiber (CPF) which consists of alternate concatenations of HNLF and single-mode fiber. Discussing the features of CPF, we show that CPF is a truly practical and flexible solution for optical pulse compression. Finally, we refer to a new class of pulse compression called "the stationary rescaled pulse (SRP)", which is a characteristic nonlinear stationary pulse propagating through CPF. The propagation characteristics of the SRP provides a systematic and efficient design method of CPF as well as optical pulse compression that has never been achieved by conventional pulse compression schemes. As an example, a highly steep pulse compression in CPF is demonstrated, where a pulse is compressed by a factor of 2.1 per step of the CPF, and a 7.2 ps-width optical pulse is compressed to 0.38 ps with a four-step structure of CPF.

“…Several researchers have carried out experiments to either compress the optical temporal width or suppress the supermode noise to improve the laser stability. These schemes include (1) adiabatic soliton compression techniques [3][4], (2) multiple-step compression based on self phase modulation in highly nonlinear fibers or semiconductor optical amplifiers (SOA) [5][6], (3) a comb-like profiled fiber (CPF) to emulate dispersion decreasing fiber [7][8], (4) saturable optical absorbers such as nonlinear optical loop mirror (NOLM) [9][10][11].…”

Mode locked pulse generation has been reported using both active and passive mode locking schemes. Active mode locking technique has been proven to be an effective way to generate high-repetition-rate pulses by incorporating a modulator inside the laser cavity. Compared to actively mode locked lasers, passively mode locked lasers can generate pulse train at ultrashort pulse width but with relatively lower repetition rate. Thus, it is a brilliant idea to build a hybrid mode locked system combining both active and passive mode lockers. In this review, several hybrid mode locked fiber ring laser systems are discussed and summarized. Hybrid mode locking is a promising method to generate high speed ultrashort optical pulses for fiber-optic telecommunication system.

“…1 for the soliton pulse train generation, a series of research has been implemented to analyze this cascaded structure. [2][3][4][5][6][7][8][9] CDPF is generally composed of a number of alternating lengths of high and low dispersion fibers [i.e., single mode fibers (SMFs) and dispersion shifting fibers (DSFs)] in which the dispersion effect and nonlinearity effect are spatially separated. 2 However, since the calculation and optimization for the dispersion, nonlinearity, and length of each fiber in CDPF are complex, a comb-like profiled fiber (CPF) was introduced to simplify the interconnected structure by using only two types of fibers, SMF and high nonlinearity fiber (HNLF).…”

Abstract. Subpicosecond pulse spectral compression without the limitation of the adiabatic soliton transform status in a comb-like distributed fiber (CDF) is proposed and numerically demonstrated. The principle of spectral compression in a single concatenation of single-mode fiber and high nonlinear fiber is theoretically analyzed and numerically proved. A three-stage CDF is designed and simulated following the principle. The simulation results show that an overall spectral compression ratio of 56.23 is obtained. The designed three-stage CDF is used in an all-optical analog-to-digital system to improve the quantization resolution to 7.1 bit. © The Authors.
