Photonic crystal fibres for chemical sensing and photochemistry

Abstract

In this review, we introduce photonic crystal fibre as a novel optofluidic microdevice that can be employed as both a versatile chemical sensor and a highly efficient microreactor. We demonstrate that it provides an excellent platform in which light and chemical samples can strongly interact for quantitative spectroscopic analysis or photoactivation purposes. The use of photonic crystal fibre in photochemistry and sensing is discussed and recent results on gas and liquid sensing as well as on photochemical and catalytic reactions are reviewed. These developments demonstrate that the tight light confinement, enhanced light-matter interaction and reduced sample volume offered by photonic crystal fibre make it useful in a wide range of chemical applications.

Alcohol sensing over O+E+S+C+L+U transmission band based on porous cored octagonal photonic crystal fiber

“…At the beginning time, PCF has limited applications areas. Now PCF is used in fields of THz telecommunications [13], nonlinear optics [14], bio sensing [15], chemical sensing [16,17], spectroscopy [18], optical chromatography [19], and fuel adulteration detection [20]. In medical science, it is becoming more and more popular for bio-photonics [21] and neurophotonics [22].…”

Glassy Materials and Light: Part 2

“…Desta forma, o preenchimento do núcleo de uma fibra de núcleo oco (Figura 12(a)) é, em princípio, mais atrativo do que o preenchimento da casca de uma fibra de núcleo sólido (Figura 12(b)), caso em que uma superposição de no máximo ~ 10% é obtida. 94,95 Entretanto, ressalta-se que em casos em que se deseja detectar apenas espécies adsorvidas na superfície, 96,97 as fibras de núcleo sólido são mais atraentes.…”

Fiber-Based, Injection-Molded Optofluidic Systems: Improvements in Assembly and Applications

“…Our system was made by the quick and simple integration of a hollow core fiber (HC fiber) [18] between two chips, where the hollow core can be filled with different liquid samples by pumping liquid from alternate ends of the HC fiber, as described by Khetani et al [8]. The system (including the HC fiber) was initially filled by pumping milli-Q water into Chip 1 at a rate of 230 μL/min (see Materials and Methods for experiment diagram).…”
