Innovative Lab on Fiber dosimeters for ionizing radiation monitoring at ultra-high doses

Georgi Gorine, Federico Ravotti

We report on a innovative Lab on Fiber (LOF) dosimeter for ionizing radiation monitoring at ultra-high doses. The new dosimeter consists in a metallo-dielectric resonator at sub-wavelength scale supporting localized surface plasmon resonances realized on t ...

Plug-and-play TOF-PET Module Readout Based on TDC-on-FPGA and Gigabit Optical Fiber Network

Edoardo Charbon, Esteban Venialgo Araujo

Positron Emission Tomography (PET) scanner technology requires the use of a large number of PET detector modules that work in a parallel and synchronous manner. Moreover, system modularity is a desirable feature, that enables technology reutilization for d ...

Phase Sensitive OTDR Strain Measurement Using Single Mode Operation in Multimode OM4 Fiber

Luc Thévenaz, Zhisheng Yang, Alejandro Dominguez Lopez

We present the first realization of strain sensing in a multimode OM4 optical fiber using phase-sensitive optical time-domain reflectometry. We demonstrate that single mode operation in an OM4 fiber is achievable and allows the fiber strain to be measured ...

Distributed hydrostatic pressure measurement using phase OTDR in a highly birefringent photonic crystal fiber

Luc Thévenaz, Li Zhang

Although distributed fiber-optic sensing of axial strain and temperature is a well-established technique, there are almost no demonstrations of distributed hydrostatic pressure sensing. The main obstacle for such measurements is the low sensitivity to pres ...

Large stimulated Brillouin scattering amplification in gases

Luc Thévenaz, Flavien Gyger

We exploit backward stimulated Brillouin scattering in gases to achieve unprecedented nonlinear optical amplification in fibers. The gain coefficient is 10 times larger than any reported nonlinear gain in gas-filled HC-PCF and 6 times larger than the large ...

Photoinitiator-free multi-photon fabrication of compact optical waveguides in polydimethylsiloxane

Demetri Psaltis, Christophe Moser, Giulia Panusa, Ye Pu, Jieping Wang

Compact, low loss flexible optical waveguides are crucial in optofluidic and microfluidic devices for a dense integration of optical functionalities. We demonstrate the fabrication of compact optical waveguides in polydimethylsiloxane through multiphoton l ...

A comparative study of mode I delamination behavior of unidirectional glass fiber-reinforced polymers with epoxy and polyurethane matrices using two methods

John Botsis, Georgios Pappas

The mode I delamination behavior of a unidirectional glass-fiber reinforced polymer with a prototype elasto-plastic polyurethane matrix (GF/PU) was investigated and compared with that of glass/epoxy (GF/EP) using double cantilever beam specimens. Fracture ...

Dissipative dispersion-managed solitons in fiber-optic systems with lumped amplification

Anton Lukashchuk

We numerically and experimentally studied the shape of the dissipative dispersion-managed solitons (DM-solitons) stably propagating over the lossy DM fiber-optic systems with lumped amplification. We found that, contrary to the lossless case, the chirp-fre ...

Optimization of Spin-Wave Propagation with Enhanced Group Velocities by Exchange-Coupled Ferrimagnet-Ferromagnet Bilayers

Dirk Grundler, Vinayak Shantaram Bhat, Kyongmo An

We report broadband spectroscopy and numerical analysis by which we explore propagating spin waves in a magnetic bilayer consisting of a 23-nm thick permalloy film deposited on 130-nm thick Y_3Fe_5O_12. In the bilayer, we observe a characteristic mode that ...
