“…In some cases, it is desirable to suppress SSFS in order to maintain spectrum center frequency and to achieve high signal coherence. Takara et al [71] reported a field demonstration of 1046 channel DWDM transmission with a supercontinuum multicarrier source spanning 1.54 mm to 1.6 mm, which was mainly generated through SPM-induced spectral broadening. The channel spacing was 6.25 GHz and the signal data rate per channel was2.67 Gb/s.…”

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.

“…The mid-infrared spectral domain ranging from 2 to 20 μm is particularly important because of not only it contains two important windows (3-5 μm and 8-13 μm spectral region) in which the earth's atmosphere is relatively transparent but also the strong characteristic vibrational transitions of most of the molecules are in this domain [2]. Mid-infrared molecular 'fingerprint region' is applicable in various important applications in different diverse fields such as medical, industry and security [3][4][5][6][7].…”

2015): Design and analysis of equiangular spiral photonic crystal fiber for mid-infrared supercontinuum generation, Journal of Modern Optics, A design of equiangular spiral photonic crystal fiber (PCF) in As 2 Se 3 chalcogenide glass is reported for mid-infrared supercontinuum generation. Supercontinuum covering the 1.2-15 μm molecular fingerprint region is achieved using only 8 mm long designed PCF pumped with 50 fs laser pulses of 500 W peak power. The structural parameters have been tailored for all-normal dispersion characteristic. Proposed structure has high nonlinearity (γ = 12474 W −1 km −1 ) at 3.5 μm with very low and flat dispersion −2.9 [ps/(nm × km)]. Supercontinuum with such broadening and high coherence degree is applicable for mid-infrared spectroscopy, gas sensing, early cancer diagnostics and free space communication.

“…Generation of over-10000-channel multi-carriers by using SC-MCLS was reported in [6]. Based on SC-MCLS, over-1000-channel ultra-dense WDM transmission was demonstrated [7,8]. However, how to design cost-effective and high-performance optical networks with MCLS is still an open question.…”

A resilient star-ring optical broadcast-and-select network with a centralized multi-carrier light source

This article presents a resilient star-ring optical broadcast-and-select network with a centralized multi-carrier light source (C-MCLS). It consists of a star part network and a ring part network. Optical carriers generated by the C-MCLS are broadcast to all network nodes, which select and utilize them for data transmission. Optical carrier distribution as well as data transmission and receiving are performed in the star part network. The ring part network is for fiber failure recovery. The network resilience property enables the design of a fast distributed failure recovery scheme to deal with single and multiple fiber failures. We introduce a fiber connection automatic protection switching (FC-APS) architecture that only consists of optical couplers and 1×2 optical switches for each network node. Based on the FC-APS architecture, we design a distributed failure recovery scheme to recover the carriers and data affected by fiber failures. The fiber failure detection and failure recovery operations are performed by each network node independently only using its local information. We evaluate the recovery time of the distributed failure recovery scheme compared with that of the centralized one. Numerical results show that the distributed scheme greatly reduces the recovery time compared to the centralized configuration in the recoveries of both single and multiple fiber failures. Optical power loss analysis and compensation of the recovery routes in the distributed scheme are also presented. We show the required number of optical amplifiers for the longest recovery route in the distributed
