In this paper we study the behavior of Internet traffic on the AS-level topology and discuss its implications on interdomain traffic engineering. We rely on two notable interdomain traffic traces, the first is one month long and the other is one day long. This study shows that interdomain paths are stable for a large majority of the traffic from a routing(More)
In this paper, we describe the design, optimization and fabrication of side-illuminated p-i-n photodetectors, grown on InP substrate, suitable for surface hybrid integration in low-cost modules. The targeted functionalities of these photodetectors were a very high responsivity at 1.3and 1.55m wavelengths and quasi-independent on the optical polarization,(More)
We demonstrated the potential application of III-V/polymer nanowires for photonic integrated circuits in a previous paper. Hereby, we report the use of a spot size converter based on 2D reverse nanotaper structure in order to improve the coupling efficiency between the nanowire and optical fiber. A total coupling enhancement of up to a factor 60 has been(More)
We present the design, optimization, fabrication and characterization of an optical mode filter, which attenuates the snaking behavior of light caused by a lateral misalignment of the input optical fiber relative to an optical circuit. The mode filter is realized as a bottleneck section inserted in an optical waveguide in front of a branching element. It is(More)
An in-depth study of metal assisted chemical etching (MACE) of p-type c-Si in HF/H2O2 aqueous solutions using Pt nanoparticles as catalysts is presented. Combination of cyclic voltammetry, open circuit measurements, chronoamperometry, impedance spectroscopy, and 2D band bending modeling of the metal/semiconductor/electrolyte interfaces at the nanoscale and(More)

After a review of conventional microwave photodetectors, this paper is dealing with the difficulties to fulfill applications requirements (responsivity, bandwidth, power), when the bandwidth is extended up to the millimeter wave frequency range. Up to date solutions are given and the validity of a new concept, the PIN photodiodes evanescently coupled to a(More)
We analyze waveguide InP photodetectors for millimeter wave applications. We start with the PIN waveguide photodetector pointing out key problems like optical coupling, microwave access and maximum available power. To benefit from an internal gain we introduce the waveguide InP heterojunction phototransistor showing its ability to operate up to 60 GHz.
