The process of cold drawing a fiber over rollers is analyzed in this work to predict the temperature rise due to the heat generated during plastic deformation of the fiber. Experimental measurements on prototypes indicated an unacceptable temperature rise of greater than 100 F requiring ... Read More
Near-field scanning optical microscopy (NSOM) combines the potential of scanning probe technology with the power of optical microscopy and provides us with eyes for the nanoworld. NSOM probes require a subwavelength optical aperture with wide cone angle of the probe to efficiently ... Read More
The remarkable power scaling of high power fiber lasers over the past years has become more and more challenging, because the effects of transverse mode instability (TMI) and photodarkening (PD) of the fiber are limiting the effective output power of typical industrial fiber lasers. The ... Read More
This paper presents multiphysics modeling of coupled thermal-electrical behavior across the composite joints formed by highly anisotropic conductivity materials such as carbon fiber reinforced polymers (CFRP) under lightning strike conditions and demonstrates the driving physics behind ...

Hydrophones are acoustic receivers, which can be used to listen to the sound propagating underwater for the purposes of monitoring marine life, or other sound producing activities in the sea. Commonly used hydrophones are based on piezoelectric transducers. With the introduction of fiber ... Read More
Optical fibers that can deliver mid-infrared light in a wide wavelength range are in high demand due to their significant potentials in sensors, chemical imaging, optoelectronics and nonlinear optics applications. Semiconductors such as Ge, ZnSe and Si are good infrared-transparent ... Read More
The detection of early corrosion is a key issue to mitigate the damage induced by metal corrosion. The optical fiber corrosion sensor based on a side-polished polarizer is realized recently. The polarizer is fabricated by sputtering a Fe film on a side-polished single mode fiber. The new ... Read More
The use of lasers to fragment and remove kidney stones (Laser Lithotripsy) has become increasingly popular in surgical procedure due to its high success rate and minimal complications. However, the precise mechanisms behind the stone fragmentation process are not yet fully understood. ... Read More
The transducer's construction used for current measurement in medium voltage power lines for current values kA is shown. The transducer involves magnetic circuit with a gap in which a MEMS structure with a movable cantilever is placed. The beam is made of silicon with a NiFe layer. The ... Read More
The EPFLoop team from Ecole Polytechnique Fédérale de Lausanne has developed a capsule thanks to which it achieved 3rd place in SpaceX’s Hyperloop Pod Competition in 2018. This year the EPFLoop team has been selected again to participate at the 2019 Competition held at the SpaceX ... Read More
