For the development of minimized and high-rate photonic-integrated fiber Bragg grating interrogation (FBGI) systems, arrayed waveguide grating (AWG) ... transmission spectrum with crosstalk below −16 ...

In the company's Direct Grating Writing process, two focused UV lasers are overlapped to give a small circular spot with an inherent linear interference pattern. Modulating the beam as it scans a ...

For this reason, the researcher developed a concept to reduce the bandwidth and stabilize the wavelength of the laser radiation. Once again, a directly inscribed fiber Bragg grating is central to this ...

The innovation presented in this article is the use of fiber Bragg grating strain gage readings to identify the dynamic features of a long-span, steel-girder bridge. ... Huang J, Zhou Z, Zhang L, et ...
