“…But in contrast to only one-step process of fabrication of "molten-core" fibers 13,14,15 based on other non-silica core materials, phosphate glass enable us to fabricate at a first stage small-diameter-core preforms. As a result, long fiber samples with small diameter variations could be drawn.…”

We describe composite optical fibers with rare-earth co-doped phosphate-glass core in a silica-glass cladding. High REion concentrations in the phosphate core of the composite fiber allow fiber length reduction in comparison with silica fibers. The silica cladding provides high mechanical strength and protects the phosphate core from air moisture while making it easier to splice with silica fibers.

“…[ 124 ] Other materials have been drawn with a similar approach such as Ge, InSb, or even sapphire derived all-glass optical fi bers. [125][126][127] At such high temperature, effects such as diffusion, chemical reactions and the formation of grain boundaries upon cooling and solidifi cation can be expected. This was recently highlighted in work where an aluminium rod inside a silica cladding at the preform level resulted in a Silicon core and alumina domains in the fi ber.…”

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.

“…In 2012 a sapphire-derived fiber was reported as a structured all-glass fiber with an aluminosilicate core [6], which was originally investigated for its very small Brillion gain coefficient. The inscription of gratings into this special kind of fiber with an aluminum oxide content of 30 mol% was reported, but without a proof of high temperature stability.…”

Optical Bragg grating sensor fibers for ultra-high temperature applications

Sapphire based optical fibers provide an attractive basis for ultra-high temperature stable optical sensor elements. Fiber Bragg gratings can be inscribed in such fibers by means of femtosecond-laser pulses with a wavelength of 400 nm in combination with a two-beam phase mask interferometer. We have investigated crystalline optical fibers as well as structured sapphire-derived all glass optical fibers with aluminum content in the core of up to 50 mol%. The reflection properties, the index modulation and the attenuation effects will be discussed. Results concerning the temperature and strain sensitivity for use as sensor elements at high temperatures will be presented.
