“…[ 10,11 ] These microstructured fi bers include single or arrays of longitudinally invariant air holes of defi ned and various diameters, allowing the manipulation of the propagation of light inside the fi bers in unique ways. Examples of such fi bers, which are also referred to as microstructured optical fi bers (MOFs), include hollow core photonic bandgap fi bers [12][13][14] and endlessly single mode fi bers, where the latter guides the light in a single optical mode for any combination of wavelength and core diameter. [ 15 ] All the mentioned fi ber structures have now reached a technologically high level with the consequence that a large fraction of current MOF-related research focuses on the applications of MOFs rather than on new fi ber geometries, which holds in particular for the fi eld of solid-core fi bers.…”

The field of hybrid optical fibers is one of the most active research areas in current fiber optics and has the vision of integrating sophisticated materials inside fibers, which are not traditionally used in fiber optics. Novel in‐fiber devices with unique properties have been developed, opening up new directions for fiber optics in fields of critical interest in modern research, such as biophotonics, environmental science, optoelectronics, metamaterials, remote sensing, medicine, or quantum optics. Here the recent progress in the field of hybrid optical fibers is reviewed from an application perspective, focusing on fiber‐integrated devices enabled by including novel materials inside polymer and glass fibers. The topics discussed range from nanowire‐based plasmonics and hyperlenses, to integrated semiconductor devices such as optoelectronic detectors, and intense light generation unlocked by highly nonlinear hybrid waveguides.

“…The hollow-core optical fibre gas laser (HOFGLAS) -proposed and demonstrated by Jones/Nampoothiri [30,31] -combines the attractive properties of compactness, long interaction length and low lasing threshold of fibre laser and potential for high power and narrow line-width of gas laser. The lasing medium is optically pumped gas molecules filled in hollow-core (HC) photonic crystal fibre.…”

The field of gas lasers, started with the invention of He-Ne laser in 1961, has witnessed tremendous growth in terms of technology development, research into gaseous gain medium, resonator physics and application in widely diverse arenas. This was possible due to high versatility of gas lasers in terms of operating wavelengths, power, beam quality and mode of operation. In recent years, there is a definite trend to replace the gas lasers, wherever possible, by more efficient and compact solid-state lasers. However, for many industrial, medical and military applications, the gas lasers still rule the roost due to their high-power capabilities with good beam quality at specific wavelengths. This chapter presents a short review covering the operating principle, important technical details and application potential of all the important gas lasers such as He-Ne, CO 2 , argon ion, copper vapour, excimer and chemical lasers. These neutral atoms, ions and molecule gas lasers are discussed as per applicable electrical, chemical and optical excitation schemes. The optically pumped gas lasers, recently experiencing resurgence, are discussed in the context of far infrared THz molecular lasers, diode-pumped alkali lasers and optically pumped gas-filled hollow-core fibre lasers.

“…The composition and morphology of fibrous materials play an important role in determining their functions. For instance, changing the material composition of fibers alters the features of the resulting textile, and the design of the inner cores of an optical fiber determines the efficiency of optical communication . In many researches, complex compositions and morphologies can be achieved by postcoating on the fiber, by pulling the bulk composite material into fibers, or by various spinning methods …”

This paper presents mechanically reinforced low‐concentration alginate fibers by embedding inner cores of high‐concentration alginate. 3D structures by stacking multiple polydimethylsiloxane (PDMS) layers allow the microfluidic formation and control of the isolated cores in the continuous flow. The alginate hydrogel fibers are simply spun, and the compartments, central core, surrounding cores, and outer shell layer are successfully verified. The results demonstrate the great potential for the development of complex fibrous materials, particularly for biological applications, which require specific morphology and composition of the fibers.
