Impact of the fiber coating on the temperature response of distributed optical fiber sensors at cryogenic ranges

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Xin Lu

The thermomechanical behavior of a standard single mode fiber with different coating materials is theoretically analyzed under different temperature conditions. Results show that the thermal expansion/shrinkage of the fiber coating introduces an extra stra ...

Opto-acoustic chemical sensor based on forward stimulated Brillouin scattering in optical fiber

Luc Thévenaz, Desmond Chow Ming Chia

Stimulated Brillouin scattering is well-known for providing distributed measurements in the field of optical fiber sensing. For the conventional backward stimulated Brillouin scattering, the sensing capability is nevertheless limited to temperature and mec ...

All-optical flip-flops based on dynamic Brillouin gratings in fibers

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Andrey Denisov

A method to generate an all-optical flip-flop is proposed and experimentally demonstrated based on dynamic Brillouin gratings (DBGs) in polarization maintaining fibers. In a fiber with sufficiently uniform birefringence, this flip-flop can provide extremel ...
