摘要

A new tunable optical delay scheme based on real-time Fourier transformation and ramp-type phase modu-nlation is proposed and experimentally demonstrated. A linearly chirped ﬁber Bragg grating is adopted tonimplement the real-time Fourier transformation, and tunable delay is realized by changing the ramp-typenmodulating signal’s period. Experimental results agree well with the theory. The signal distorts little afternthe delay, and a 18 ps delay is achieved for a 2-ps-wide optical pulse. © 2010 Optical Society of America
