Narrow-linewidth multi-wavelength random distributed feedback laser
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this work, narrow-band emission lines are generated by means of two random distributed feedback fiber laser schemes. Spectral line-widths as narrow as 3.2 pm have been measured, which significantly improves previous ...
Compound lasing fiber optic ring resonators for sensor sensitivity enhancement
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this work, a new method for increasing simultaneously the sensitivity and interrogation stability of fiberoptic intensity sensors is presented. The configuration is based on a double-coupler ring resonator. On one side, ...
