In this review paper some recent advances on optical sensors based on photonic crystal fibres are reported. The different strategies successfully applied in order to obtain feasible and reliable
These sensors work based on advanced and flexible phototonic crystal fiber (PCF) structures, controlled light propagation for the measurement of
For each kind of optical sensor, the specific measurement principle, structure of PCC, and the corresponding sensing properties are all presented in detail.
A characteristic feature of photonic crystal fibers, which makes these particular interesting for sensor applications is the close proximity of samples positioned in the air holes and light guided through the
Photonic Crystal Fibers (also called holey fibers, hole-assisted fibers, microstructure fiber, or microstructured fibers) are specialty fibers containing tiny air holes which enable the formation of
This article reviews the recent progress in optical sensors using photonic crystal fiber (PCF) technology, which is newly adopted beyond conventional optical fibers (OFs) due to their unique geometric
In this work, the process of designing and simulating optical sensors based on photonic crystal (PC) micro-ring resonators (MRRs) has been investigated.
An ultra-sensitive photonic crystal optical fiber sensor based on surface plasmon resonance (SPR) is designed and analyzed. The D-shaped optical fiber is symmetrically coated with two layers of gold
In this review, the fundamentals and fabrication of PCF infiltrated with different materials are discussed. In addition, potential applications of infiltrated PCF sensors are reviewed, identifying
Photonic crystal fibers can be divided into two modes of operation, according to their mechanism for confinement: index guiding and photonic bandgap. Index guiding photonic crystal fibers are
Photonic crystal fibers (PCF) are defined as a type of optical fiber that guides light through a two-dimensional photonic crystal structure, utilizing mechanisms such as photonic bandgap or index
In PCFs, the light is confined by a periodic pattern of microstructured air holes running along the fiber, thus allowing lower losses. By engineering the geometric array of air holes, the
