Wireless optical technology like visible light communication is a new approach in terms of security, speed, usability, bandwidth and flexibility for data communication. More and more people with their devices access wireless internet today, due to which clogged airwaves are going to make transmission slow and is full of interference. The solution to this problem of slow speed is that data is to...

In this paper, an enhancement design of communication system using optical radio frequency (RF) waves in free space optical communication (FSO) system is presented. To our knowledge, it is the first time that the effect of Gamma-Gamma turbulent channel model on the performance of the proposed system is analyzed and simulated. To obtain an optical communication system with good performance and h...

In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...

Time-domain numerical analysis of nonlinear propagation in Slow-Wave-Structures, focused on the interplay of enhanced third-order nonlinearity with chromatic dispersion has been carried on. In dependence on the operating conditions, a tunable optical oscillator/pulse train generator and an optical limiter have been designed. Morphological inspection and functional characterization at λ=1.5 μm o...

In Malaysia, fiber cable is commonly installed underground or overhead. Once optical fibre cable is installed either underground or over-head, there is no physical maintenance implemented. The only maintenance on fibre cable is the monitoring of optical fibre attenuation. Bend loss affects the attenuation and any bending cable that contributes to the bend loss remains unmaintained since there i...

Single-mode fibres with low loss and a large transmission bandwidth are a key enabler for long-haul high-speed optical communication and form the backbone of our information-driven society. However, we are on the verge of reaching the fundamental limit of single-mode fibre transmission capacity. Therefore, a new means to increase the transmission capacity of optical fibre is essential to avoid ...

Introduction: Orthogonal-frequency-division-multiplexing (OFDM) is a special form of multicarrier modulation where a single data stream is transmitted over a number of lower rate orthogonal subcarriers [1]. Such a format has been widely implemented in various digital communication standards. Recently we proposed an equivalent optical multicarrier modulation format, called coherent optical OFDM ...

Stimulated Brillouin scattering (SBS) is a recent technique developed to generate slow light in optical fibres. It is the simplest and most applicable method of slow light production. In this paper a high power laser pump was used to provide the Brillouin gain of a low power signal of -10 dBm. Three single mode fibres namely, standard fibre (STD), large area fibre (LA) and reduced slope fibre (...
