Abstract :
Efficient and low cost dispersion compensation is necessary to achieve useful transmission distances in optical communication systems at bit rates above 10 Gb/s. In the paper, we present a novel method for dispersion compensation that uses three fiber gratings in series. This method eliminates the requirement for an optical circulator, commonly used in grating-based dispersion compensators. As a result, our device is inexpensive to fabricate and have a low insertion loss. We present a theoretical model that predicts how the efficiency of the device can be maximized. We also present experimental results showing complete dispersion compensation for 30-ps pulses, broadened to 67 ps by propagating through 10 km of standard, singlemode fiber
