The Development of a Highly Sensitive Fiber-Optic Oxygen Sensor
Abstract: This paper presents a highly sensitive fiber-optic oxygen sensor. The sensor was fabricated using palladium (II) meso-tetrakis (pentafluorophenyl) porphyrin (PdTFPP) and porous silica nanoparticles embedded in a tetraethylorthosilane (TEOS)/n-octyl-triethoxysilane (Octyl-triEOS) composite xerogel present as a coating on the end of the fiber. Sensitivity is quantified in terms of the r...
متن کاملDevelopment of a Fringe Sensor based on 3x3 Fiber Optic Coupler for Space Interferometry
Large stellar telescope is indispensable for astronomy. Aperture synthesis is a well-known technique to simulate a large space telescope by an array of small telescopes. Condition for aperture synthesis is that the light of the telescopes have to be combined coherently. Therefore, an interferometric Fringe Sensor (FS) to detect and stabilize the Optical Path Difference (OPD) between light from ...
متن کاملFiber-optic modal coupler using periodic microbending.
Periodic coupling between the various modes in an optical fiber is of current interest in interferometric and sensor applications. Coupling between the two cross-polarized modes of a single-mode birefringent fiber has been studied,1 as has coupling between the LP0 1 and LP 11 modes in a circularly symmetric fiber. 2 The latter case was achieved by periodically squeezing the fiber. It has been d...
متن کاملMultimode Fiber Using Adaptive Optics
Transmitter-based adaptive optics and receiver-based single-mode filtering are combined to compensate modal dispersion in multimode fiber (MMF). A liquid-crystal spatial light modulator controls the launched field pattern for ten 10-Gb/s nonreturn-to-zero channels, wavelength-division multiplexed on a 200-GHz grid in the C-band. Error-free transmission through 2.2 km of 50m graded-index MMF is ...
متن کاملBiofunctionalization of a Fiber Optics-Based LSPR Sensor
When exposed to light, metal nanoparticles exhibit a phenomenon known as LSPR, Localized Surface Plasmon Resonance. The wavelengths at which LSPR occurs is very dependent on the refractive index of the surrounding medium. Binding of biomolecules to the surface of gold nanoparticles result in a change in the refractive index that can be detected spectrophotometrically by monitoring the LSPR peak...
