Introduction: 160 Gbit=s optical time domain multiplexing (OTDM) technology is only interesting if full add-drop functionality can be realised on the existing fibre infrastructure [1]. A 160 Gbit=s OTDM add-drop node based on the gain transparent ultrafast nonlinear interferometer (GT-UNI) has been demonstrated under laboratory conditions [2]. In this Letter we present a 160 Gbit=s OTDM network...

By using hybrid fibre radio (HFR), a method in integrating wireless and optical networks, large part of the radio complexity can be transferred to a central office deeper in the network. This paper presents a novel approach in deploying IEEE 802.11 wireless local access network (WLAN) through integration with HFR. We will discuss its applications, a brief review of the individual technologies, ...

Multiple broadband services are carried independently in a highly multimode polymer optical fibre network by selectively launching and detecting several mode groups, while counteracting mode-mixing by adaptive electrical signal processing. With cheap integrated signal processors, mode group diversity multiplexing can offer the same functionality as wavelength multiplexing at lower costs. © 2002...

Conventional contact sensors used for Lamb wave-based ultrasonic inspection, such as piezo-electric transducers, measure omnidirectional strain and do not allow distinguishing between fundamental symmetric and anti-symmetric modes. In this paper, we show that the use of a single fibre Bragg grating created in a dedicated microstructured optical fibre allows one to directly make the distinction ...

This paper demonstrates the first single optical fibre tip probe for concurrent detection of both hydrogen peroxide (H₂O₂) concentration and pH of a solution. The sensor is constructed by embedding two fluorophores: carboxyperoxyfluor-1 (CPF1) and seminaphtharhodafluor-2 (SNARF2) within a polymer matrix located on the tip of the optical fibre. The functionalised fibre probe reproducibly measure...

In this paper, we present a non-standard fibre amplifier specially designed to amplify scar modes of a multimode chaotic optical fibre. More precisely, we introduce Ytterbium in the optical fibre as a gain medium localised on the maximum of intensity of the scar modes. After briefly recalling the relevance of a chaotic optical fibre as a device to visualise quantum chaos, we describe the amplif...

Reproducible, precise cleaving of optical fibres is of great importance to the fibre laser and telecommunications industries. We present a novel approach to the end-face processing of optical fibres using a 9.6 µm CO2 laser to produce flat, smooth and symmetric fibre end-face profiles with no rounding or melting at the edges of the fibre. As a demonstration, precision cleaving of a 4...
