Embedded coupler based on selectively infiltrated photonic crystal fiber for strain measurement.
A photonic crystal fiber (PCF) with embedded coupler is demonstrated for strain measurement. The embedded coupler is constructed by the selective filling of one of the air holes in the PCF. Light propagated in the fiber core can be efficiently coupled to the liquid-filled rod waveguide under phase-matching conditions, resulting in sharp decreasing of resonant wavelength intensity. The highest s...
متن کاملHighly Sensitive Sensors Based on Photonic Crystal Fiber Modal Interferometers
We review the research on photonic crystal fiber modal interferometers with emphasis placed on the characteristics that make them attractive for different sensing applications. The fabrication of such interferometers is carried out with different post-processing techniques such as grating inscription, tapering or cleaving, and splicing. In general photonic crystal fiber interferometers exhibit ...
متن کاملTemperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures
Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...
متن کاملSlotted Photonic Crystal Sensors
Optical biosensors are increasingly being considered for lab-on-a-chip applications due to their benefits such as small size, biocompatibility, passive behaviour and lack of the need for fluorescent labels. The light guiding mechanisms used by many of them results in poor overlap of the optical field with the target molecules, reducing the maximum sensitivity achievable. This review article pre...
متن کاملTemperature insensitive long period grating sensors in photonic crystal fibre
A Long Period Grating was fabricated in endlessly single mode photonic crystal fibre using a spatially-periodic electric arc discharge. The sensing characteristics of the grating were studied and it was found to possess an insensitivity to temperature, a bend sensitivity of 3.7 nm.m and a strain sensitivity of -2.0 pm/με. Introduction: Long period gratings (LPGs) consist of a large scale (hundr...
