The mid-infrared spectral region is of great technical and scientific importance in a variety of research fields and applications. Among these studies, mid-infrared supercontinuum generation has attracted strong interest in the last decade, because of unique properties such as broad wavelength coverage and high coherence, among others. In this paper, the intrinsic optical properties of different types of glasses and fibers are presented. It turns out that microstructured chalcogenide fibers are ideal choices for the generation of mid-infrared supercontinua. The fabrication procedures of chalcogenide microstructured fibers are introduced, including purification methods of the glass, rod synthesis processes, and preform realization techniques. In addition, supercontinua generated in chalcogenide microstructured fibers employing diverse pump sources and configurations are enumerated. Finally, the potential of supercontinua for applications in mid-infrared imaging and spectroscopy is shown.

“…At present, supercontinuum light and a frequency comb are attractive light sources. (7)(8)(9) Poly(dimethylsiloxane) is used for integrating the microchannel and embedding the fibers; however the simple setting means low alignment accuracy and limited illumination efficiency.

Lifted Bottom of Microfluidic Channel for Cell Absorption Spectroscopy Using Optical Fibers

A Si microoptical bench has been developed for measuring the absorption spectrum of cells in suspension. Optical fibers are the elements for constructing a light path inside a Si chip. The sensing light is introduced, transmitted through the sample, and detected. The light propagates in the core. A thick surrounding cladding protects the beam from optical disturbance. In many cases, the cells in suspension tend to sink to the bottom of the microfluidic channel because their density is higher than that of water. For bringing the cell in the sensing light beam, the bottom of the microfluidic channel is lifted up to the core height of the optical fiber in the device. The absorption caused by the chlorophyll of the chlorella is observed.

“…Numerous studies on SC generation in an optical fiber have been carried out to cover the spectral range from ultraviolet to MIR. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Many researchers have demonstrated SC generation in a silica fiber. [5][6][7] However, the intrinsic transmission window of fused silica limits SC extension above 3 µm.…”

“…10) So far, many researchers have demonstrated MIR SC generation in Ch-SIFs. 11,[14][15][16][17][18] In 2016, Cheng et al demonstrated MIR SC extending from 2.0 to 15.1 µm in a Ch-SIF. 18) In most of the studies, broadband SC has been generated by pumping in the anomalous dispersion (AD) regime near the zero-dispersion wavelength (ZDW).…”

We experimentally demonstrate mid-infrared (MIR) supercontinuum (SC) generation in a 2.8-cm-long chalcogenide double-clad fiber (Ch-DCF). The Ch-DCF made of As2Se3, AsSe2, and As2S5 glasses has near-zero chromatic dispersion in the normal dispersion regime. We pump the Ch-DCF using a 200 fs pulse laser at 10 µm, and obtain MIR SC extending from 2 to 14 µm. Numerical results show that the Ch-DCF has the potential of generating a highly coherent MIR SC light source.
