Abstract

In this paper, an adiabatic soliton compression (ASC) compressor using a loss management fiber link (LMFL) comprised of alternating erbium-doped fiber (EDF) and ordinary single-mode fiber (SMF) is proposed. The EDF provides quasi-distributed gain instead of distributed gain provided by Raman amplification along the fiber link to compensate the fiber loss. With appropriate choice of length, segments numbers of erbium fiber and pump power, ASC will be realized. The input optical pulse will get narrower through adiabatic soliton compression effect when it propagates in the LMFL. Numerical simulation shows that a fundamental soliton pulse with repetition rate, width and peak power of 40GHz, 10ps and 478mW, respectively, can be compressed to a 1.40ps-width pulse with small pedestal by using the LMFL. The main advantages of this method are as follows: Firstly, by changing the pump power of EDF, the compressed optical pulses with different compression factor can be obtained. Secondly, compared with other adiabatic soliton compression techniques based on Raman amplification, dispersion-decreasing fiber or comb-like dispersion profiled fiber, this method is easy to control and costs less.
