Photonic crystal fibers are a new class of optical fibers. Their artificial crystal-like microstructure results in a number of unusual properties. They can guide light not only through a well-known total internal reflection mechanism but using also photonic bandgap effect. In this paper different properties possible to obtain in photonic crystal fibers are reviewed. Fabrication and modeling methods are also discussed.

“…In particular, the field of fiber-optic sensors, along with the continuing research and development of optical fibers in the broad field of communications, has attracted considerable interest because optical fibers take many advantages from inherent properties such as superior sensing abilities, miniaturization feasibility, resistance to chemical corrosion, and robust immunity to electromagnetic interference (EMI). Since the early inventions of fiber-optic gyroscopes and acoustic sensors, a great deal of effort has been made to explore valuable sensing applications with benefits resulting from the innovation of advanced optical fiber technologies [1][2][3][4][5]. For example, intensity-based fiber sensors, fiber Bragg grating (FBG) sensors, coherence interferometric sensors, and Brillouin scattering distributed sensors have been investigated for accurate and reliable operation even in various harsh or hazardous areas ranging from chemical plants, nuclear power generation plants, oil reservoirs, aerospace, to bio-organisms.…”

Novel breakthrough random-hole optical fibers (RHOFs) are fabricated in a draw tower facility, by tapering an optical fiber preform packed with a silica powder mixture capable of producing air holes in situ at the high temperature of tens of hundreds in degrees Celsius. Structural and propagation characteristics of the porous RHOF are explained briefly. Experimental investigations of the invented RHOF are performed for pressure sensor applications. Remarkable results are obtained for the RHOF with desirable pressure sensitivity independent of temperature, as is required for harsh conditions as in oil reservoirs.

“…In 2000, Gander et al 4 proposed a two-axis bend measurement using multicore optical fiber. MacPherson et al 5 demonstrated a curvature sensor using a twin-core photonic crystal fiber, and Flockhart et al 6 reported two-axis bend measurement using Bragg gratings written in multicore optical fiber.…”

Abstract.We describe an all-fiber Mach-Zehnder interferometric configuration based on a suspended twin-core fiber. Because of the birefringence of the fiber cores, two interferometers are obtained by illuminating the fiber with polarized light. Applying strain, curvature, and temperature to the sensing head, different sensitivities are observed that permit the use of the matrix method to discriminate these three measurands.
