Stratophase, a spin-off from Southampton University in the UK, has developed a technique to simultaneously write a waveguide and a planar Bragg grating into an optical silicon chip. The technology has ...

However, diode lasers emit broadband radiation. For this reason, the researcher developed a concept to reduce the bandwidth and stabilize the wavelength of the laser radiation. Once again, a directly ...

In this study, fiber Bragg grating strain gages were installed on the lower chord members of a bridge, and dynamic features were identified successfully using strain gage readings when vehicles passed ...

For the development of minimized and high-rate photonic-integrated fiber Bragg grating interrogation (FBGI) systems, arrayed waveguide grating (AWG) has been widely used as one of the critical ...
