Superconducting nanowire photon-number-resolving detector at telecommunication wavelengths

Francis Lévy, Konstantinos Lagoudakis, Francesco Marsili, Alessandro Gaggero

Optical-to-electrical conversion, which is the basis of the operation of optical detectors, can be linear or nonlinear. When high sensitivities are needed, single-photon detectors are used, which operate in a strongly nonlinear mode, their response being i ...

Fundamentals and challenges of optical multiple-input multiple-output multimode fiber links [Topics in Optical Communications]

Ali H. Sayed, Arvind Shah

In this article we discuss the application of MIMO processing to multimode fiber links. MIMO processing is shown to increase the information capacity of communication links linearly as the minimum number of transmitters/receivers increases. The fundamental ...

Photoacoustic spectroscopy for multi-gas sensing using near infrared lasers

Jean-Philippe Besson

Photoacoustic spectroscopy is a widely recognised technique to measure trace gases at parts-per-million (ppm) or parts-per-billion (ppb) level using semiconductor laser in the near infrared range. This technique is based on the generation of an acoustic wa ...

Ultrafast photonic crystal nanocavity laser

Hatice Altug

Spontaneous emission is not inherent to an emitter, but rather depends on its electromagnetic environment. In a microcavity, the spontaneous emission rate can be greatly enhanced compared with that in free space. This so-called Purcell effect can dramatica ...

Impact of Pseudonym Changes on Geographic Routing in VANETs

Panagiotis Papadimitratos

Inter-vehicle communication is regarded as one of the major applications of mobile ad hoc networks (MANETs). In these so called vehicular ad hoc networks (VANETs) security and privacy are crucial factors for successful deployment. In a scenario, where each ...

High-speed Si resonant cavity enhanced photodetectors and arrays

Yusuf Leblebici, Paul Victor Georges Muller

Over the past decade a new family of optoelectronic devices has emerged whose performance is enhanced by placing the active device structure inside a Fabry–Perot resonantmicrocavity [P. E. Green, IEEE Spectrum 13 (2002)]. The increased optical field allows ...

Study of vertical coupled-cavity laser structures

This thesis addresses general aspects of the operation of a coupled-cavity vertical surface-emitting laser (CC-VCSEL) which consists of two active cavities optically coupled and independently electrically pumped. The first two chapters of the thesis deal w ...

Fault Localization at the WDM layer

Jean-Yves Le Boudec, Patrick Thiran, Carmen Mas

A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM), the number of alarms and the difficul ...
