Slow Light with Photonic Crystals for On-Chip Optical Interconnects
Figure 5
When an
index shift is induced in one arm of the interferometer, the group velocity in
that arm changes. The pulses traveling in the two arms of the interferometer
therefore arrive at the output separated in time by , resulting in
pulse distortion (broadening). In the worst case, where the pulses interfere
destructively, the output pulse can even become double-humped (inset).
