Fiber optic pressure sensing with conforming elastomers.
Fiber optic pressure sensing conforming elastomers.
2013/5/27
A novel pressure sensing scheme based on the effect of a conforming elastomer material on the transmis-sion spectrum of tilted fiber Bragg gratings is presented. Lateral pressure on the elastomer incr...
Highly-Birefringent Tunable Long-Period Fiber Gratings in Hollow-Core Photonic Bandgap Fiber by Use of Mechanical Pressure
Gratings Fiber optics Photonic crystal fibers
2015/6/4
The mode coupling properties of highly-birefringent tuneable LPGs formed in HC-PBGF are presented. The mode coupling from the fundamental core mode to higher-order guided mode of a HC-PBGF is obtained...
Temperature sensor based on a pressure-induced birefringent single-mode fiber loop mirror.
optical fiber sensor fiber loop mirror pressure-induced birefringence temperature sensor
2013/5/27
A fiber-optic temperature sensor based on a pressure-induced birefringent single-mode fiber(SMF) loop mirror is developed. The pressure-induced birefringent SMF is made by applying a force against a s...
Novel Optical Fiber Identification Method for PONs Based on Polarization Modulation Caused by Pressure-Induced Retardation
Optical Fiber PONs Polarization Modulation Caused Pressure-Induced Retardation
2015/7/17
We proposed a new technique for identifying fibers in PONs using polarization-modulation caused by a transverse force. We demonstrate our method using conventional and bend-insensitive fibers in a bra...
Atmospheric Pressure Deposition of Silica Thin Film by Photo-CVD Using Vacuum Ultraviolet Excimer Lamp
Excimer lamp Silica thin film TEOS
2009/6/8
It has been known that thin silica films can be deposited from TEOS {Si(OC2H5)4} by means of the photo-CVD (Chemical Vapor Deposition) technique using vacuum ultraviolet (VUV) light (VUV-CVD) at room ...

Influence of Eu dopant on optical properties of TiO2 thin films fabricated by low pressure hot target reactive sputtering
titanium oxide europium
2011/5/4
This work presents the influence of europium dopant on optical properties of TiO2:Eu3+ thin films fabricated by low pressure hot target reactive sputtering. Thin films were deposited from metallic Ti-...
Pressure induced microbends have been created in a 50 mm graded index multimode optical fibre with spatial periodicity L = 4.5 mm, embedded in the sample of araldite. If high pressure is applied direc...
High pressure spectroscopy of Pr3+ doped KLa(MoO4)2 crystal
Department of Physics,Kaximierz Wielki University,Weyssenhoffa 11,85-072 Bydgoszcz,Poland
2011/5/3
Optical properties and electronic structure of Pr3+ ion in KLa0.75Pr0.25(MoO4)2 have been investigated. The standard spectroscopy (excitation and photoluminescence spectra) and the high pressure spect...
Influence of high pressure annealing on electrical properties of surface layer of neutron irradiated or germanium-doped Czochralski-grown silicon
germanium-doped silicon neutron-irradiated silicon defects
2011/4/27
The effect of annealing at 720–920 K under enhanced pressure (up to 1.1 GPa) in argon ambient on electrical properties of the surface layer of the Czochralski-grown silicon (Cz-Si) subjected to neutro...
