Hi everyone
I want to increase the sensitivity of fbg sensors in optigrating software. Can anyone come up with a complete solution? I just want to increase the sensitivity of the fbg sensors and do not want to use lpfg sensors. please help me.
thanks.

      I can recommend putting the sensing segment inside a Bragg cavity. i.e. two gratings in the stop band in sequence. The spectral properties of a Bragg cavity are very sensitive to changes in the cavity.

      Hi, steve
      Can you give me a sample simulation file on this?
      thanks.
