State-of-the-art optical fiber communication system reaches to transmission capacity from tens to hundreds of Tb/s. The massive capacity crunch has sparked concerns regarding available bandwidth and constantly increasing optical data traffic. Certainly, one way is to broaden the spectral transmission range beyond the narrow gain band of current erbium doped fiber amplifier (EDFA). Either side of Erbium across low-loss transmission window (1.5μm) shown promising results with optical fibres codoped with rare-earth-doped materials such as bismuth/thulium. Hence, it is of crucial importance to develop broadband optical amplifier to fully utilize the uncovered spectral regions with proper choice of pump wavelength(s)/Laser diodes. Here we have compared the performances of Bismuth/Erbium and Ytterbium/Erbium co-doped fibres as pumped to 808nm to one as pumped at 830nm. The pumping excitation conditions and spectral characteristics in BEDF and EYDF are explored to maximize the lasing efficiency. Using equivalent conditions and same section of Bi/Er codoped fiber, an enhanced broadband emission with FWHM ~ 149 nm is observed in Bi active centers (BAC) related to Si around ~1420nm under 808nm excitation as compared to 830nm with its FWHM ~ 125nm at an input power of ~ 55.5 mW. At maximum power, under 808nm pumping, a well-known peak emission of Er³⁺ at 1536nm noticeably increased due to reabsorption of BAC-Si (~1420nn) with the ratio ~ 1.7 between Er³⁺ and BAC-Si emission peaks. On the contrary, emission peak of the BAC-Si revealed higher with the ratio of ~ 1.5 than that of Er³⁺ by 830nm pumping. Afterward, we observed Yb³⁺ emission at 1040nm and 980 nm using Yb/Er codoped fiber with both pumps at same power. Using 808nm pumping, an extended emission band around ~ 1230 nm appeared namely BAC-Al while the other emission bands associated with BAC-Si (~ 1480nm) and Er³⁺ (~1536nm) shown similar emission bands with high emission peaks compared to 830nm pump at equivalent pump powers. Furthermore, the emission peak of the BAC-Si is about the same level as that of Er³⁺ with ratio of RBi/Er~ 1.1 under 808nm pumping while 830 nm pump showed the ~ 5.25 ratio between the emission peaks of BAC-Si and Er³⁺. We believe that this side-by-side comparison of two pumps and two home-made fabricated codoped fibres could be useful as a promising strategy for the next-generation WDM passive optical networks employing single broadband amplifier and tunable fiber laser covering 1000-1800nm telecommunication bands.

Liquid-level sensing technologies have attracted great prominence, because such measurements are essential to industrial applications, such as fuel storage, flood warning and in the biochemical industry. Traditional liquid level sensors are based on electromechanical techniques; however they suffer from intrinsic safety concerns in explosive environments. In recent years, given that optical fiber sensors have lots of well-established advantages such as high accuracy, costeffectiveness, compact size, and ease of multiplexing, several optical fiber liquid level sensors have been investigated which are based on different operating principles such as side-polishing the cladding and a portion of core, using a spiral side-emitting optical fiber or using silica fiber gratings. The present work proposes a novel and highly sensitive liquid level sensor making use of polymer optical fiber Bragg gratings (POFBGs). The key elements of the system are a set of POFBGs embedded in silicone rubber diaphragms. This is a new development building on the idea of determining liquid level by measuring the pressure at the bottom of a liquid container, however it has a number of critical advantages. The system features several FBG-based pressure sensors as described above placed at different depths. Any sensor above the surface of the liquid will read the same ambient pressure. Sensors below the surface of the liquid will read pressures that increase linearly with depth. The position of the liquid surface can therefore be approximately identified as lying between the first sensor to read an above-ambient pressure and the next higher sensor. This level of precision would not in general be sufficient for most liquid level monitoring applications; however a much more precise determination of liquid level can be made by linear regression to the pressure readings from the sub-surface sensors. There are numerous advantages to this multi-sensor approach. First, the use of linear regression using multiple sensors is inherently more accurate than using a single pressure reading to estimate depth. Second, common mode temperature induced wavelength shifts in the individual sensors are automatically compensated. Thirdly, temperature induced changes in the sensor pressure sensitivity are also compensated. Fourthly, the approach provides the possibility to detect and compensate for malfunctioning sensors. Finally, the system is immune to changes in the density of the monitored fluid and even to changes in the effective force of gravity, as might be obtained in an aerospace application. The performance of an individual sensor was characterized and displays a sensitivity (54 pm/cm), enhanced by more than a factor of 2 when compared to a sensor head configuration based on a silica FBG published in the literature, resulting from the much lower elastic modulus of POF. Furthermore, the temperature/humidity behavior and measurement resolution were also studied in detail. The proposed configuration also displays a highly linear response, high resolution and good repeatability. The results suggest the new configuration can be a useful tool in many different applications, such as aircraft fuel monitoring, and biochemical and environmental sensing, where accuracy and stability are fundamental.
