Progress and challenges in industrial fabrication of wafer-fused VCSELs emitting in the 1310 nm band for high speed wavelength division multiplexing applications

Elyahou Kapon, Grigore Suruceanu, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic, Dalila Ellafi

Building coarse wavelength division multiplexing (WDM), 4x10 Gbps VCSEL transmitter modules has the promise for dramatic decreasing power consumption. Over the last years, we have demonstrated continuous improvements of parameters and reliability of wafer ...

Mitigating modulation instability in Brillouin distributed fibre sensors

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Wei Chen, Mohammad Mehdi Alem Karladani

A thorough study of the generation of modulation instability (MI) in distributed Brillouin fibre sensors is presented. ASE noise co-propagating with the pump pulses within the MI gain spectrum has been identified to be an important factor seeding modulatio ...

A micro particle shadow velocimetry (mu PSV) technique to measure flows in microchannels

John Richard Thome, Giulia Tagliabue, Navid Borhani, Sepideh Khodaparast

A micro particle shadow velocimetry (mu PSV) system based on back-lit illumination and forward scatter observation of light from non-fluorescent particles has been developed. Relatively high luminous efficiencies and particle image contrasts were achieved ...

A combined experimental/numerical study of the scaling effects on mode I delamination of GFRP

Anastasios Vassilopoulos, John Botsis, Behzad Dehghan Manshadi

Bridging by intact fibers is an important toughening mechanism in composite materials. However, a direct experimental evaluation of its contribution is difficult to achieve and in the case of large scale bridging the thickness, h, may have an important inf ...

Dynamic bending compensation while focusing through a multimode fiber

Demetri Psaltis, Christophe Moser, Salma Farahi, David Ziegler

Multimode fiber endoscopes have recently been shown to provide sub-micrometer resolution, however, imaging through a multimode fiber is highly sensitive to bending. Here we describe the implementation of a coherent beacon source placed at the distal tip of ...

A CMOS-compatible silicon photonic platform for high-speed integrated opto-electronics

Yi Zhang, Christophe Marcel Georges Galland, Yang Liu, Qi Li, Ran Ding

We have developed a CMOS-compatible Silicon-on-Insulator photonic platform featuring active components such as p- i-n and photoconductive (MIM) Ge-on-Si detectors, p-i-n ring and Mach-Zehnder modulators, and traveling-wave modulators based on a p-n junctio ...

Increasing the imaging capabilities of multimode fibers by exploiting the properties of highly scattering media

Demetri Psaltis, Christophe Moser, Salma Farahi

We present a design that exploits the focusing properties of scattering media to increase the resolution and the working distance of multimode fiber (MMF)-based imaging devices. Placing a highly scattering medium in front of the distal tip of the MMF enabl ...

Focusing and scanning light through a multimode optical fiber using digital phase conjugation

Demetri Psaltis, Christophe Moser, Salma Farahi

We demonstrate for the first time to our knowledge a digital phase conjugation technique for generating a sharp focus point at the end of a multimode optical fiber. A sharp focus with a contrast of 1800 is experimentally obtained at the tip of a 105 mu m c ...

SPDC based single-photon source with frequency up-conversion multiplexed architecture

Vincent Frédéric Camus

We describe a single-photon source based on an array of spontaneous parametric down-conversion (SPDC) modules multiplexed by an integrated structure composed of electro-optic switches and delay wave-guides. The suggested optical device allows to increase t ...
