Papers by Keyword: Chirped Fiber Grating

Abstract: In order to compensate the dispersion in 40Gb/s optical links, the optical dispersion compensation is discussed because of its high compensation speed and small nonlinear. An optical equalizer, in post compensation, is presented and the results based on simulations show that an equalizer consisting of chirped fiber grating can mitigate dispersion effectively by setting the incident power from 6 to 8dBm.

Abstract: In this paper, a novel strain sensor based on chirped fiber grating with temperature compensation is presented. The proposed strain sensor uses double chirped fiber gratings. The temperature compensation exploit the principle that the wavelength shifts of these two chirped fiber gratings induced by temperature is consistent. This strain sensor is demodulated by the light intensity detection with low cost. Furthermore, the strain sensor is simulated in the end of this paper.
