Germanium and Silica co-deposition in MCVD process is studied with varying the flow ratio of GeCl4/SiCl4 at high temperature without phosphorus. The range of ratio is from 0.1 to 0.6 with temperature deposition 2100°C. The incorporation of germanium in silica matrix is deduced from the EPMA SEM-EDX. The experimental result is compared to theory such as thickness deposited layer and mole fraction of germanium in silica.

The work presented in this paper is on a backward-pumped Raman random distributed feedback laser with half-opened cavity configuration. Rayleigh backscattering effects were realized in a 41 km fiber length that functioned as a virtual mirror at one fiber end while at the other end, a single fiber Bragg grating with different central wavelength is deployed as a reflector. Pump power threshold, output power and efficiency that corresponding to FBG wavelengths of 1546.8 nm, 1550.4 nm and 1557.7 nm are studied. The obtained results show that the peak reflection wavelength of FBG nearest to the first Raman Stokes shift gives better threshold and output power, hence, improves the efficiency of random lasing.

This paper describes our 1.06um pulsed laser source which has the capability to generate pulses with tunable durations from picoseconds to nanoseconds. This is made possible through the use of a high speed Field Programmable Gate Array (FPGA) board to generate the required pulses/ any arbitrary waveforms. The FPGA codes are specially designed to generate very fast rise/fall times waveforms with the flexibility to vary both the pulse duration and pulse frequency in real time. These custom defined waveforms are then used to generate high intensity laser pulses when connected to a 1064nm fiber laser source. These tunable pulsed laser sources have potential industrial applications in precision laser micro machining, where the high thermal intensity of the laser pulses can be used to perform ablation, cutting, drilling or annealing of processed materials. Furthermore, by able to tailor the shape of the delivered laser pulses, this will lead to reduction in processing time, improves the efficiency of material removal and the quality of the end product. Our custom board can generate arbitrary tailored pulses as short as 200ps and the longest pulse is 200ns. The pulse repetition rate can be tuned from 20 kHz to 1MHz.

A real-time, centralized and cost efficient monitoring and fault localization system is presented. In this system, a superluminescent diode (SLED) is used as the monitoring signal and the signal is reflected by using different types of fiber Bragg gratings (FBGs); uniform and phase-shifted FBGs as branch identifiers. We demonstrate the enhancement of monitoring wavelength whereas for a distinct center wavelength, it represents the reflection spectrum of two types of FBG or two branches in the network. Thus, more optical network units (ONUs) can be monitored for the specific monitoring source with limited bandwidth. The system is capable to monitor up to 64 ONUs with BER of 10-15.

In recent years intensive research has shown broadband luminescence in the range of 1100 to 1500 nm, across O, E and S bands of the telecommunications window from glasses or materials with Bi-doping and Bi/Er codoping. This presentation will report our research on active optical fibres based on new material compositions incorporating Bi, Er and Al into phosphogermanosilicate glasses. Emission and absorption are two main properties of active optical fibers that are of interest for fiber amplifiers and lasers. Hence, we report the recent development of Bi/Er/Al codoped phosphogermanosilicate optical fibres showing ultra broadband luminescence between 1000 and 1570 nm, covering O, E, S, C, and L bands, when pumped by 532, 808, or 980 nm lasers. This type of new material composition optical fibres is designed for potential use as an ultra broadband gain medium for ultra broadband amplified spontaneous emission (ASE) sources, tunable fibre lasers, or ultra broadband amplifiers in telecommunications and in other fields.

Gain of Raman-amplified four-wave mixing (FWM) signals in optical fibers was found to be different from less than the third power of the signal gain at and near spectral positions of local minima when the spacing of two input signals is a few nm. The gain there was enhanced which was unaccountable with theoretical analyses. It is likely that wavelength regions corresponding to dips are sensitive to the distribution of local Raman gain and that increased Raman gain for FWM signals was caused by anisotropic Raman gain over a fiber.

Two tunable multiwavelength Brillouin-Raman fiber lasers in the long-band region utilizing both linear and ring cavities were compared. The effect of Raman pump power on the performance parameters of the two cavities was investigated. At 10 dBm Brillouin pump power, up to 41 single spacing channels were obtained in the linear cavity, compared with only six double spacing Stokes signals in the ring cavity. Tuning ranges reached 27 and 49 nm at the optimum Raman pump powers of 325 and 400 mW for the linear and ring laser cavities, respectively. The ring cavity exhibited better Stokes power fluctuation of 0.491 dB compared with the 1.045 dB fluctuation in the linear cavity.

Nonlinear optical properties of 2- (2-hydroxyethyl)-6-(morpholin-4-yl) -1H-benzo[de]isoquinoline- 1,3(2H)- dione pigment material is investigated with frequency modulation of 250 MHz femtosecond high repetition rate (HRR) laser by an optical chopper. Thermal lensing formation on the material due to thermal build up from HRR laser leads to measurement ambiguity of nonlinear refractive index (NLRI) and two-photon absorption cross section (TPACS). Optimized optical chopper frequency range of 50% duty cycle modulated laser beam effectively reduces laser contact time on the material and resulted in improved NLRI and TPACS of -8.23 × 10-18 m2/W and 2.96 GM respectively.

Multiwavelength Brillouin erbium fiber laser (BEFL) in a new linear cavity structure have been demonstrated. The BEFL cavity was formed by a double pass amplification box on one side and a virtual mirror installed on the other side. The double pass amplification box reduces the threshold power and enhances Stokes line generation. By utilizing dispersion compensating fiber (DCF) to act as a virtual mirror, the self lasing cavity modes that limits the tuning range of the ordinary BEFL is efficiently eliminated. At Brillouin pump power of 5 dBm and EDF pump power of 90 mW, up to 14 Stokes lines and a wide tuning range of 40 nm, from 1529 nm to 1569 nm, free from the self lasing cavity modes, were obtained.

Fiber tip lens technology has been employed to reduce coupling loss in fiber to Micro Fabry Perot Multiplexer (FP MUX) and fiber to Micro Fabry Perot Demultiplexer (FP DEMUX) connection. The convex type of fiber tip lens is proposed for FP MUX coupling connection while the concave type of fiber tip lens for FP DEMUX coupling connection. Finite Difference Time Domain (FDTD) numerical method simulation model for 50 μm and 65 μm radius of fiber tip lens have been developed for coupling loss performance analysis. In this analysis, Dense Wavelength Division Multiplexing (DWDM) light ranging from 1270 nm to 1610 nm wavelength has been launched onto the fiber tip lens and lens characteristic is done in terms of focus distance and beam size. Coupling loss analysis shows extremely low loss has been achieved, which are below 6 nW and 0.3 nW for 65 μm radius of convex and concave type of fiber tip lens respectively. This analysis contributes to an optimal configuration of lens in FP MUX and FP DEMUX connection with minimal coupling loss.
