FBG wide-range and high rate interrogation method

Giordana, Alejandro; Sicre, Enrique; Duchowicz, Ricardo (2014-07)

A FBG sensor interrogation method for measuring applications requiring a wide wavelength range and a high rate interrogation is presented. An optical intensity transfer with a cosine-like shape is obtained by a fiber ...
Phase and amplitude measurements for high bandwidth optical signals

Bulus-Rossini, Laureano; Costanzo Caso, Pablo; Paulucci, Emanuel; Duchowicz, Ricardo; Sicre, Enrique (2014-08)

In this paper a novel technique for obtaining the amplitude and phase of optical pulses with time extents as short as tens of ps is presented. The method which is based on the transport-of-intensity equation only requires, ...
