Graded index optics

WebThe transmission of information along optical fibers is normally achieved by sending out a sequence of pulses of light energy. However, as an individual pulse propagates, it spreads out, due to the dispersive properties of the fiber. Clearly if this spread becomes sufficiently large the pulse will overlap with adjacent pulses, leading to a ...
