“…The multi-reflection process that happen in the tapered based EDF is unique and it produces a transfer function much different from the other interferometer such as Fabry-Pérot [22,23], Michelson and Sagnac configurations [24,25]. The narrow core along the fiber phase is extremely high sensitivity and relatively low loss and for this reason, the tapered based EDF filter has a greater sensitivity and one of the best results to produce multiwavelength laser compared to the other techniques.…”

This paper presents a multiwavelength fiber laser utilizing non-adiabatic tapered EDF based Mach Zehnder Interferometer (MZI) in hybrid Raman-EDF gains design with a linear cavity. A stable laser was obtained from the single pump with a 1497 nm wavelength through the employment of a 20:80 optical circulators and 99% reflective mirror. The generated backward propagating oscillates inside the laser cavity generate the stable multiwavelength output with 4 channels, which is coupled out via the 10:90 coupler and the output laser is characterized using an OSA with a resolution of 0.015 nm. The hybrid Raman-EDF gain is pumped from the external cavity by a Raman Pump Unit (RPU) and produced a stable multiwavelength laser output with SMSR of 28.9 dBm for 300 mW pump power, 30.7 dBm for 1000 mW pump power and 33.7 dBm for 1500 mW pump power.

“…This concept is well studied and employed in optics [4][5][6] to build highly precise micro/nano sensors able to locally measure for example acoustic strain, 7 temperature 8 or pressure. 9 In the field of acoustics, the strong impedance contrast between fluid and enclosed gas as well as the huge amplification or absorption properties at resonance find numerous applications. In medicine, impedance contrast is clinically exploited in ultrasonography through the use of contrast agents.…”

International audienceThis letter reports on a method for producing on demand calibrated bubbles in a non-chemically controlled solution using localized micro-electrolysis and ultrasound. Implementing a feedback loop in the process leads to a point source of stable mono-dispersed microbubbles. This approach overcomes the inertial constraints encountered in microfluidics with the possibility to produce from a single to an array of calibrated bubbles. Moreover, this method avoids the use of additional surfactant that may modify the composition of the host ﬂuid. It impacts across a broad range of scientific domains from bioengineering, sensing to environment

“…The sensor, based on an optical fibre Fabry Perot interferometer (EFPI) approach, often used in a number of sensing applications such as temperature, acoustic wave sensing, pressure and liquid level sensing [15,16] will be used to measure pressure underwater. However, EFPI sensors often provide a very high level of sensitivity of single particular physical parameters, but suffer from cross sensitivity, e.g., temperature [17].…”

Abstract:A miniature sensor for accurate measurement of pressure (depth) with temperature compensation in the ocean environment is described. The sensor is based on an optical fibre Extrinsic Fabry-Perot interferometer (EFPI) combined with a Fibre Bragg Grating (FBG). The EFPI provides pressure measurements while the Fibre Bragg Grating (FBG) provides temperature measurements. The sensor is mechanically robust, corrosion-resistant and suitable for use in underwater applications. The combined pressure and temperature sensor system was mounted on-board a mini remotely operated underwater vehicle (ROV) in order to monitor the pressure changes at various depths. The reflected optical spectrum from the sensor was monitored online and a pressure or temperature change caused a corresponding observable shift in the received optical spectrum. The sensor exhibited excellent stability when measured over a 2 h period underwater and its performance is compared with a commercially available reference sensor also mounted on the ROV. The measurements illustrates that the EFPI/FBG sensor is more accurate for depth measurements (depth of~0.020 m).
