A time-deterministic inter-module communication architecture for embedded computer systems is presented. The architecture is general in the sense that a bit-parallel word of any size is transferred from/to the processing unit via the communication unit on/from the shared medium. To get a time-deterministic communication the communication is executed cyclically and the resources (time slots and ...

The Optical communication network offers very high potential bandwidth and flexibility In terms of high bit-rate transmission. However, their performance slows down due to some parameter like dispersion, attenuation, scattering and unsynchronized bit pattern. A chromatic dispersion compensator plays an essential role in the optical fiber communications system in order to recover the degraded tr...

Optical microelectromechanical systems (MEMS) combine miniature optical components with precision fixtures, elastic suspensions, and microactuators, and allow complex functionality at low cost. However, the effect of the bounded nature of the beams propagating through the system on design is profound. The current paper reviews the fundamental consequences. Using a Gaussian beam formulation, mod...

Optical fibres have already played a huge part in ground based astronomical instrumentation, however, with the revolution in photonics currently taking place new fibre technologies and integrated optical devices are likely to have a profound impact on the way we manipulate light in the future. The Anglo Australian Observatory, along with partners at the Optical Fibre Technology Centre of the Un...

We present a co-axial dual-core resonant leaky optical fibre design, in which the outer core is made highly leaky. A suitable choice of parameters can enable us to resonantly couple power from the inner core to the outer core. In a large-core fibre, such a resonant coupling can considerably increase the differential leakage loss between the fundamental and the higher order modes and can result ...

Pressure induced microbends have been created in a 50 μm graded index multimode optical fibre with spatial periodicity Λ = 4.5 mm, embedded in the sample of araldite. If high pressure is applied directly to optical fibre having microbends, it may break, and if pressure is applied to embedded fibre in a solid structure without microbends, the sensitivity is lower. In this paper, a combination of...

In recent years there have been rapid advances in the techniques to generate and transport radio signals over optical fibre, however very little has been done to date to develop the concept of a full duplex, multi-wavelength, radio -over-fibre network architecture that intrinsically supports and facilitates the dynamic reconfiguration of the wireless network. Recently the development of suitabl...
