“…where δ 1 and δ 2 are the stress-induced birefringence intensity of the two modes, and Ω stands for the angle of the fast axis orientation of the PC with respect to the x polarization component assuming the same orientation angle for the two modes. The saturable or reverse saturable absorption of GIMF satisfies [22][23][24] ∆β n L + ϕ = mπ,…”

Reverse saturable absorption is essential for the realization of dissipative solitons. In this paper, we introduce reverse saturable absorption by using nonlinear multimode interference (NL-MMI), for the first time, to the best of our knowledge, and obtain a stable dissipative soliton operation. By adjusting the coupling efficiency from multimode fiber to single mode fiber, the absorption properties of NL-MMI can be switched between saturation and reverse saturation. The dissipative soliton in the experiment can be obtained with pulse width of 975 fs, the 3 dB bandwidth with 1555 nm is 16 nm, and the maximum output power is 11.48 mW. The nonlinear absorption optical modulation and high damage threshold characteristics of NL-MMI based ultrafast optical switch provide a new idea for realizing dissipative solitons.

“…This ultrafast optical switch realized by changing the coupling efficiency not only does this independent of polarization state, but also has a high damage threshold. Modelocking based on NL-MMI has been successfully applied to traditional mode-locking, dissipative soliton mode-locking, and Q-switching [21][22][23][24][25][26] . In the previous study of our group, this method is also used to achieve HML by introducing 150 m long SMF in the cavity [27] .…”

Harmonic mode-locked fiber laser based on microfiber-assisted nonlinear multimode interference

A novel harmonic mode-locked fiber laser based on nonlinear multimode interference (NL-MMI) in a microfiber-assisted ultrafast optical switch is proposed in this Letter. The microfiber-assisted ultrafast optical switch can be obtained by tapering the splicing point of the graded-index multimode fiber (GIMF) and single-mode fiber, which not only helps to shorten the self-imaging period in GIMF to relax the strict requirement of NL-MMI on the length of multimode fiber, but also improves the harmonic order. In the experiment, with the waist diameter of ∼15 μm, the repetition rates of the fiber laser can be stably locked at 285 MHz, corresponding to the 16th-order harmonic mode-locking, with the pulse duration of 1.52 ps. Our results provide novel insight into the design of a high-repetition-rate laser and the application of microfibers in the modelocking device.

“…Another major source for nonlinearities is the use of high input optical power level which is required to minimize the number of repeaters in a long haul link [ 3 ]. Because of the components that have nonlinear transfer function, the aggregated distortion to the signal becomes manifold and, hence, causes severe performance degradation [ 4 , 5 ]. Cross phase modulation (XPM) [ 6 ], four wave mixing (FWM) [ 7 ], and self phase modulation (SPM) [ 8 ] are the key nonlinear impairments in optical fiber communication system, which needs to be mitigated for reliable and error-free transmission.…”

High capacity long haul communication and cost-effective solutions for low loss transmission are the major advantages of optical fibers, which makes them a promising solution to be used for backhaul network transportation. A distortion-tolerant 100 Gbps framework that consists of long haul and high capacity transport based wavelength division multiplexed (WDM) system is investigated in this paper, with an analysis on different design parameters to mitigate the amplified spontaneous emission (ASE) noise and nonlinear effects due to the fiber transmission. The performance degradation in the presence of non-linear effects is evaluated and a digital signal processing (DSP) assisted receiver is proposed in order to achieve bit error rate (BER) of 1.56 × 10−6 and quality factor (Q-factor) of 5, using 25 and 50 GHz channel spacing with 90 μm2 effective area of the optical fiber. Analytical calculations of the proposed WDM system are presented and the simulation results verify the effectiveness of the proposed approach in order to mitigate non-linear effects for up to 300 km length of optical fiber transmission.
