2023年2月3日 · Optical fiber sensors working at the dispersion turning point (DTP) have served as promising candidates for various sensing applications due to their ultrahigh sensitivity. In this review, recently developed ultrasensitive fiber sensors at the DTP, including fiber couplers, fiber gratings, and interferometers, are comprehensively analyzed.

2024年10月1日 · Three main methods for DTP implementation in optical fiber sensors are introduced. The aim is to provide effective methods for superior performance of turning point-enhanced optical fiber RI sensors. The potential strategy of turning point effect for biosensing applications is assessed.

2023年6月15日 · Herein, we develop an all-fiber dispersion turning point (DTP)-enhanced PTI gas sensor with a taper-based mode interferometer in which the PT phase detection sensitivity of the interferometer is enhanced in a millimeter-long single fiber …

2023年9月1日 · A CO 2 laser-induced LPFG in the DTP has been proposed, which provides a low-cost and simple way to replace femtosecond and UV lasers, and breaks the limitation that CO 2 laser could not fabricate LPFG with shorter period.

We investigate maximising optical fibre network capacity, using new wavelength bands and fibres, and research in nonlinear optics, information theory, space division multiplexing, machine learning and digital signal processing.

2018年1月8日 · Two phenomena for enhancing the sensitivity of long-period fiber gratings are combined toward an increase of the sensitivity to strain of this type of devices: the dispersion turning point (DTP) and the cladding diameter reduction by an etching process.

2023年10月16日 · We demonstrated a cross-sensitivity-free torsion and strain sensor, which was achieved by using the two concatenated dispersion-turning-point (DTP)-customizable helical long-period fiber gratings (DTP-C-HLPGs).

2023年2月3日 · In this review, recently developed ultrasensitive fiber sensors at the DTP, including fiber couplers, fiber gratings, and interferometers, are comprehensively analyzed. These three schemes are...

2023年2月3日 · However, the authors should pay more attention to the sensing applications using the DTP fiber-optic devices. For instance, the DTP-based LPFGs and tapered optical fibers, as a typical DTP fiber-optic device, have been widely reported for sensing in the literature.

Digital textile printing is considered the 'next generation' printing, significantly different from conventional fabric printing methods. With fabric printing going digital, many textile...
