We theoretically model the transmission of ultra-short optical pulses by FabryPerot interferometer, taking into account multiple waves re-reflection inside interferometer by examination of two superimposed waves. Based on the analytical and numerical analysis, we calculate the transformations of the optical electric field profiles and optical spectra of the pulses at the output of the interfero...

A review for optical fiber sensors based on fiber ring laser (FRL) demodulation technology is presented. The review focuses on the principles, main structures, and the sensing performances of different kinds of optical fiber sensors based on FRLs. First of all, the theory background of the sensors has been discussed. Secondly, four different types of sensors are described and compared, which in...

We demonstrate feed-forward vibration isolation on a suspended Fabry-Perot interferometer using Wiener filtering and a variant of the common least mean square adaptive filter algorithm. We compare the experimental results with theoretical estimates of the cancellation efficiency. Using data from the recent Laser Interferometer Gravitational Wave Observatory (LIGO) Science Run, we also estimate ...
