“…Fiber lasers capable to produce broad and flat supercontinuum (SC) spectra are very attractive optical sources with important applications in many research fields, such as optical communications, biomedical research, spectroscopy and device characterization, among others [1][2][3][4][5][6][7]. Up to now, various fiber-based SC generation schemes have been proposed and demonstrated, relying on different pump light sources [8][9][10][11][12] and nonlinear optical media [12][13][14][15][16][17][18]. Among those approaches, one of the most common method for SC generation relies on injecting ultrashort optical pulses into specialty optical fibers.…”

The conditions to obtain noise-like pulses (NLPs) from a figure-eight fiber laser (F8L) and their application for supercontinuum (SC) generation in the anomalous dispersion regime are reported. The F8L is designed to remove the undesired low-intensity background radiation from pulse emission, generating NLPs with a 3-dB spectral bandwidth of 17.43 nm at the fundamental repetition frequency of 0.8 MHz. After amplification, NLPs reach a maximum average power of 9.2 mW and 123.32 nm spectral bandwidth. By controlling the amplifier pump power, flat SC generation is demonstrated through both a 800-m long spool of SMF-28 fiber and a piece of 5-m long highly nonlinear optical fiber. The results demonstrate a satisfactory flatness of 3-dB over a bandwidth of 1000 nm in the range from 1261 to 2261 nm, achieving to the best of our knowledge, one of the flattest SC generated from noise-like pulses.

Since atomically thin two-dimensional (2D) graphene was successfully synthesized in 2004, it has garnered considerable interest due to its advanced properties. However, the weak optical absorption and zero bandgap strictly limit its further development in optoelectronic applications. In this regard, other 2D materials, including black phosphorus (BP), transition metal dichalcogenides (TMDCs), 2D Te nanoflakes, and so forth, possess advantage properties, such as tunable bandgap, high carrier mobility, ultra-broadband optical absorption, and response, enable 2D materials to hold great potential for next-generation optoelectronic devices, in particular, mid-infrared (MIR) band, which has attracted much attention due to its intensive applications, such as target acquisition, remote sensing, optical communication, and night vision. Motivated by this, this article will focus on the recent progress of semiconducting 2D materials in MIR optoelectronic devices that present a suitable category of 2D materials for light emission devices, modulators, and photodetectors in the MIR band. The challenges encountered and prospects are summarized at the end. We believe that milestone investigations of 2D materials beyond graphene-based MIR optoelectronic devices will emerge soon, and their positive contribution to the nano device commercialization is highly expected.

Supercontinuum light sources with both highly flatness and highly coherence have unique application advantages in biological imaging, optical frequency comb, and optical coherence tomography. We demonstrate the generation of a highly coherent flat supercontinuum spectrum. In order to achieve broadband flat spectrum generation, we used a highly nonlinear fiber with a nominal dispersion of zero at 1550 nm and a dispersion slope of less than 0.025 ps/(nm2·km). Meanwhile a sub 100 fs fiber laser was used as the pump source in the experiment to achieve good coherence. When the pump power was 134 mW, the supercontinuum emission was characterized between 1197 nm and 2242 nm, showing the flat spectrum with 10 dB uniformity was obtained at the wavelength region of 1603–2242 nm and wide spectrum with a conversion efficiency over 85%. The coherence of the supercontinuum spectrum was 1 in the range of 1200–2242 nm by theoretically studying the coherence characteristics of the supercontinuum spectrum. In addition, the effect of pump laser duration on spectral flatness was demonstrated through experiments. Our experiment provides a feasible method for the generation of near-infrared flat highly coherence supercontinuum spectrum with all optical fibers structure.
