This paper presents the tolerance budgeting for the coarse assembly step in a novel coarse-fine strategy for micro-assembly. The final assembly step is to be performed using MEMS-based fimctionality that remains part of the product. Total tolerance build-up due to the coarse assembly and dimensional inaccuracies has been determined for the alignment of a single mode optical fibre to a laser dio...

The realization of a quantum network node matter-based qubits compatible with telecom-band operation and large-scale information processing is an outstanding challenge that has limited the potential elementary networks. We propose platform for interfacing processors comprising neutral atom arrays photons in multiplexed architecture. use large array instead single mitigates deleterious effects t...

Optical networks have been widely implemented and they are usually used as the backbone of high-capacity telecommunication infrastructures. However, the nowadays traffic demand over these networks has increased in a way that congestion over the architecture is considerable. Due to the high costs of implementing new optical links, the routing and wavelength assignment process become an important...

The energy consumption in telecommunication networks is expected to grow considerably, especially in core networks. In this chapter, optimization of energy consumption is approached from two directions. In a first study, multilayer traffic engineering is used to assign energy-efficient paths and logical topology to IP traffic. The relation with traditional capacity optimization is explained, an...

We report a method to determine propagation delays of optical 10 Gb/s data traveling through a 75 km long amplified fiber link with an uncertainty of 4 ps. The one-way propagation delay is determined by two-way exchange and cross correlation of short (< 1 ms) bursts of 10 Gb/s data, with a single-shot time resolution better than 2.5 ps. We thus achieve a novel optical communications link suited...
